OPINION
In this appeal we consider what constitutes an express threat of death during a robbery under the Sentencing Guidelines, U.S.S.G. § 2B3.1(b)(2)(F), 1 and address several other trial and sentencing issues. A five count indictment charged William Wise Murray with the October 1993 armed bank robbery (Count 1) of the Columbia Teachers Federal Credit Union in Columbia, South Carolina, in violation of 18 U.S.C. §§ 2 and 2113(a) and (d) (1988). The indictment also charged Murray and Misjaanda Diszelle Johnson with the unarmed bank robberies of three other banks in Columbia (Counts 2-4) between November 5 and 19, 1993, and one attempted unarmed bank robbery (Count 5) of a bank in West Columbia, South Carolina, on November 22,1993, all in violation of 18 U.S.C. §§ 2 and 2113(a). Johnson pleaded guilty to Counts 2-5, and on appeal challenges the sentence imposed against her. Murray went to trial, and a jury convicted him of armed bank robbery but acquitted him of the remaining unarmed robbery charges. On appeal, Murray raises several evidentiary issues and also challenges the sentence imposed against him by the district court. Finding no error, we affirm.
I.
Johnson was arrested immediately after an attempted bank robbery on November 22, 1993. She admitted in a signed statement to F.B.I. agents that she and Murray had planned the four unarmed robberies between November 5 and November 22 and that Murray had driven her to each one and had picked her up after the first three robberies. The agents telephoned Murray at a number provided by Johnson. Murray voluntarily came in for questioning and orally confessed that he had driven Johnson to the four bank robberies in November. Murray also told the agents of another robbery not mentioned by Johnson when he confessed that, in October, Johnson helped him commit a bank robbery during which he used a toy gun. Murray refused to sign a written statement of his confession, but evidence of his oral statement was later admitted at his trial. A sawed-off shotgun recovered from Johnson’s belongings also was admitted as evidence at Murray’s trial. We first address Johnson’s claims of sentencing error and then Murray’s trial and sentencing challenges.
II.
On August 12, 1994, the district court sentenced Johnson to 121 months on each of the four unarmed robbery counts, to be served concurrently. 2 Johnson challenges the dis *1165 trict court’s findings that she obstructed justice, that she did not accept responsibility for her actions, and that she made an express threat of death during one robbery.
A.
The district court found that Johnson committed perjury during Murray’s trial, and enhanced her sentence two levels for obstruction of justice pursuant to U.S.S.G. § 3C1.1. Johnson challenges this enhancement on the basis that the district court failed to make a specific finding addressing each element of her alleged perjury as set forth in
United States v. Dunnigan,
— U.S. -, -,
The record reflects, and the district court properly found, that Johnson willfully gave false testimony concerning a material matter during Murray’s trial. In a signed confession Johnson stated that Murray was involved in the same robberies to which she later pleaded guilty. Nevertheless, at Murray’s trial Johnson testified that she could not remember making any statement about Murray’s involvement. She claimed that her memory was impaired because she was high on crack cocaine when she was arrested. Johnson also disavowed her signature on her written confession. The district court made several assessments of Johnson’s credibility and specifically found that Johnson lied when she denied having signed the confession. The district court also disbelieved Johnson’s testimony that she did not remember confessing, and found that Johnson “obstructed justice either by giving incorrect information to the police or else [by] lying on the [witness] stand.” (J.A. 296.)
See United States v. Barnett,
B.
Johnson next argues the district court erred by denying her a two level decrease in the offense level for acceptance of responsibility under U.S.S.G. § 3E1.1 for having admitted she committed the robberies. We defer to the sentencing court’s factual determination because it “is in a unique position to evaluate a defendant’s acceptance of responsibility.” U.S.S.G. § 3E1.1, comment, (n. 5). The Sentencing Guidelines commentary provides that an obstruction enhancement normally indicates the defendant has not accepted responsibility for her crimes.
Id.,
comment. (n. 4). Furthermore, “a defendant who falsely denies, or frivolously contests, relevant conduct that the court determines to
*1166
be true has acted in a manner inconsistent with acceptance of responsibility.”
Id.,
comment. (n. 1(a)). Although Johnson claims she accepted responsibility for her crimes by pleading guilty, during Murray’s trial she denied her earlier statement that he participated in the robberies. The district court determined that Johnson thereby intentionally misled law enforcement officers. Based on the propriety of the obstruction enhancement, we conclude that the district court did not err in determining that Johnson should not receive a downward adjustment for acceptance of responsibility.
United States v. Melton,
C.
Finally, Johnson challenges her two level sentence enhancement pursuant to U.S.S.G. § 2B3.1(b)(2)(F) for making an “express threat of death” during a robbery even though she was actually unarmed. 3 After demanding money during the November 5th robbery, Johnson told the teller: “Give me three stacks of $20’s. Don’t give me a dye pack. I have a gun pointed at you.” (J.A. 245.) When the teller was slow to respond, Johnson queried: “You think I’m playing?” Id. The district court, with opportunity to assess evidence of Johnson’s demeanor and the tone of the words used, relied on the intent of the Sentencing Guidelines to find that such a threat was an express threat of death because it would “instill in a reasonable person, who is a victim of the offense, significantly greater fear than that necessary to constitute an element of the offense of robbery.” U.S.S.G. § 2B3.1 comment, (n. 6). 4
Because Johnson contends the district court incorrectly applied the express
*1167
threat of death enhancement, we apply the “due deference” standard of review under 18 U.S.C. § 8742(e)(2).
United States v. Daughtrey,
Our holding is supported by the explanatory language of application note 6 to the commentary to § 2B3.1, which states:
An “express threat of death,” as used in subsection (b)(2)(F), may be in the form of an oral or written statement, act, gesture, or combination thereof. For example, an oral or written demand using words such as “Give me money or I will kill you”, “Give me the money or I will pull the pin on the grenade I have in my pocket”, “Give me the money or I will shoot you”, “Give me your money or else (where the defendant draws his hand across his throat in a slashing motion)”, or “Give me the money or you are dead” would constitute an express threat of death. The court should consider that the intent of the underlying provision is to provide an increased offense level for eases in which the offender(s) engaged in conduct that would instill in a reasonable person, who is a victim of the offense, significantly greater fear than that necessary to constitute an element of the offense of robbery.
U.S.S.G. § 2B3.1 comment., n. 6. The language used by Johnson is practically indistinguishable from the commentary example, “Give me the money or I will shoot you.” A bank robber who unequivocally demands money and states a gun is pointed at the teller has threatened to shoot the teller. Thus, we conclude that a threat to shoot a firearm at a person during a robbery, created by any combination of statements, gestures, or actions that would put an ordinary victim in reasonable fear for his or her life, is an express threat of death under § 2B3.1(b)(2)(F), even though the person delivering the threat is not in possession of a firearm. In so holding we adhere to the interpretation of “express threat of death” adopted by the majority of other circuits that have addressed this issue.
See United States v. France,
For the above reasons, we affirm Johnson’s sentence.
III.
Murray raises several challenges to his conviction for armed robbery of the credit *1168 union on October 25, 1993. Specifically, he contends that his in-court identification by eyewitnesses was improper, that the district court erred by allowing testimony about an oral confession Murray made to investigators, and that the court erred by admitting a sawed-off shotgun into evidence. He also challenges the district court’s finding during sentencing that he made an express threat of death, and its decision to depart above the applicable Sentencing Guidelines range based on the dangerousness of the weapon.
A.
Murray first challenges the in-court identifications of him by three eyewitnesses, arguing that these identifications in each case were tainted by an earlier, unduly suggestive identification procedure. For trial identifications, “reliability is the linchpin.”
Manson v. Brathwaite,
Six weeks after the robbery, Annette Sanders, the credit union teller, selected Murray’s photograph from a photo line-up of six individuals. She later positively identified Murray at trial as the robber. During a pre-trial motion to suppress, Murray argued that the photo line-up was unduly suggestive because “all of the photographs ‘looked different,’ ” Brief for Appellants at 23, and because Murray’s picture most closely fit Sanders’s general description of the robber. The district court denied the motion to suppress the photo line-up identification, finding nothing unduly suggested Murray. Citing
Reese v. Fulcomer,
Eyewitness identification at trial following an earlier pretrial photographic identification is permissible unless the photo lineup procedure is “‘so impermissibly suggestive as to give rise to a very substantial likelihood of irreparable misidentification.’”
Hughes,
As to the in-eourt identifications by Susan McDaniel and Jerry Cotton, respectively a credit union employee and a customer, Murray argues that the identifications were tainted because, prior to their testimony, the Government allowed these witnesses to enter the courtroom and see Murray seated at the defense table with his counsel during a break in the trial.
5
Extrapolating from
Reese,
he argues that because unar-ranged pre-trial confrontations between a victim and the defendant are not unduly suggestive,
B.
Murray next argues the district court erred by allowing the jury to learn that Murray made an oral statement to investigators informing them that he was involved in the October 1993 robbery. The statement itself was not admitted at trial. During a pre-trial motion to suppress, Murray denied confessing to the robbery and argued that the F.B.I. agents who interviewed him fabricated his statement. The district court denied the motion, finding the testimony of the F.B.I. agents sufficiently credible to go to the jury. On appeal, Murray argues that the district court erred in finding that he made such a statement.
Though Murray disagrees with the credibility determination of the district court, it is the role of the district court to observe witnesses and weigh their credibility during a pre-trial motion to suppress.
See United States v. Locklear,
C.
Murray argues that the court erred by admitting into evidence a sawed-off shotgun because the bank teller, Sanders, was not sure it was the weapon she observed during the robbery. He also contends the evidentiary foundation was inadequate because there was no rational basis from which to conclude that Murray possessed a shotgun. Thus, Murray argues the gun was inadmissible under Fed.R.Evid. 403 as unduly *1170 prejudicial. 7 We disagree.
A district court is given broad discretion in its evidentiary rulings, which are entitled to substantial deference.
Russell,
D.
Murray, like Johnson, argues the district court erred during sentencing by finding he made an express threat of death under U.S.S.G. § 2B3.1(b)(2)(F). Murray contends that merely revealing his gun to a teller was not sufficient support for the enhancement.
8
The record reflects, however, that Murray approached Sanders at her teller’s station and, referring to several stacks of money, demanded “give me that, give me that” as he displayed the butt of his shotgun to Sanders several times, and put his hand on its stock when he thought she had triggered the alarm. (J.A. 110.) In finding that Murray’s actions constituted an express threat of death and accordingly enhancing Murray’s sentence by two levels, the district court relied on application note 6 and on the same reasoning that we adopted in part II.C. above in upholding Johnson’s § 2B3.1(b)(2)(F) enhancement.
9
See, e.g., Hunn,
E.
Next, Murray challenges the extent of an upward sentencing departure imposed by the district court. The district court enhanced Murray’s sentence five levels for brandishing a firearm during a robbery,
*1171
pursuant to U.S.S.G. § 2B3.1(b)(2)(C).
10
The court also departed above the authorized guideline range and increased his sentence by six levels because of the dangerousness of the weapon used. U.S.S.G. §§ 5K2.0, 5K2.6, p.s. A court may sentence outside the guideline range when “there exists an aggravating or mitigating circumstance of a kind, or to a degree, not adequately taken into consideration by the Sentencing Commission in formulating the guidelines.” § 5K2.0. The extent of the increase under § 5K2.6 for possession of a weapon depends “on the dangerousness of the weapon, the manner in which it was used, and the extent to which its use endangered others.” During oral argument, Murray’s counsel made clear that he was not challenging the authority of the district court to impose a sentence outside of the guideline range,
11
but that his challenge on appeal was only to the extent of the upward departure. We review the reasonableness of the extent of an upward departure imposed under the Guidelines under an abuse of discretion standard.
United States v. Hummer,
The district court determined that the offense conduct guideline for robbery does not distinguish between the types of firearms used. U.S.S.G. § 2B3.1(b)(2). Because a sawed-off shotgun is more dangerous than a pistol, the court based its six level upward departure on an analogy to the distinction drawn between a pistol and a sawed-off shotgun under U.S.S.G. § 2K2.1(a), which punishes possession of a firearm by a felon. 12 This departure increased Murray’s maximum possible sentence from 168 months at offense level 33 to 327 months at offense level 39. The district court sentenced Murray to 300 months.
The district court’s use by analogy of a guideline reflecting similar conduct — possession of a shotgun — supports the reasonableness of its decision. “When departing on the basis of offense characteristics, the sentencing court should extend or extrapolate from other Guideline levels or principles, or employ analogies to closely related circumstances or conduct addressed by the Guidelines.”
United States v. Strickland,
Here, in determining the proper extent of departure, the district court properly looked to what the Sentencing Commission had considered a proper range — six levels — to distinguish between a handgun and a shotgun in a similar guideline. The district court did not abuse its discretion by departing upwards six levels based on the dangerousness of the weapon used.
IV.
For the above reasons, we affirm Johnson’s sentence and Murray’s conviction and sentence.
AFFIRMED.
Notes
. United States Sentencing Commission, Guidelines Manual, § 2B3.1(b)(2)(F) (Nov. 1993).
. The district court sentenced Johnson to the top end of the 97 — 121 month range under the Sentencing Guidelines for her criminal history category of I and a combined, or total, offense level of 30. U.S.S.G. § 5A (Sentencing Table). Johnson received her highest offense level for Count 2, the November 5, 1993, robbery of the Nations-Bank branch office on Millwood Avenue in Co *1165 lumbia. The district court calculated a base offense level of 20 for the violation of 18 U.S.C. § 2113(a) under Count 2, then increased the base offense level by 6 levels as follows: two points for taking the property of a financial institution under § 2B3.1(b)(1); two points for making an express threat of death under 2B3.1(b)(2)(F); and two points for obstructing justice by committing perjury under § 3C1.1. The combined offense level of 30 for all four counts was calculated by taking the offense level applicable to the group with the highest offense level (Count 2, offense level 26) and increasing the offense level by four levels pursuant to U.S.S.G. § 3D1.4.
. Johnson, relying on two Eleventh Circuit decisions,
United States v. Canzater,
A robber need not be armed in order to make an express threat of death. Whether a bank robber actually has a gun during the robbery is immaterial to the express threat of death determination,
United States v. Hunn,
. Commentary to the Sentencing Guidelines may be used to determine the Commission's intent in drafting a specific guideline. " ‘Commentary in the Guidelines Manual that interprets or explains a guideline is authoritative unless it violates the Constitution, or a federal statute, or is inconsistent with, or a plainly erroneous reading of, that guideline.'"
United States v. Nelson,
. Although the district court made no finding to that effect, the Government admits that "[p]rior to their testimony, during a break in the trial, both witnesses were asked to go into the courtroom and see if they recognized anyone.” Brief of Appellee at 14-15.
. The circumstances that we must consider include
the opportunity of the witnesses to view the criminal at the time of the crime, the witness' degree of attention, the accuracy of the witness’ prior description of the criminal, the level of certainty demonstrated by the witness at the confrontation, and the length of time between the crime and the confrontation.

v.
Biggers,
. Rule 403 states:
Although relevant, evidence may be excluded if its probative value is substantially outweighed by the danger of unfair prejudice, confusion of the issues, or misleading the jury, or by considerations of undue delay, waste of time, or needless presentation of cumulative evidence.
Fed.R.Evid. 403.
. Murray, like Johnson, relies on
Moore,
wherein the Eleventh Circuit stated that the threat of death "must be directly and distinctly stated or expressed rather than implied or left to inference.”
United States v. Moore,
.Sanders was five months pregnant at the time of the robbery. The evidence during sentencing showed that she was afraid Murray would shoot or kill her, and she begged him not to shoot her. The district court found the enhancement was appropriate because, among other factors, Sanders’ reaction was that of a reasonable victim in her position.
. Murray does not challenge this enhancement.
. We find support for this departure in similar cases affirming an upward departure based on the dangerous nature of the weapons possessed. For instance, in
United States v. Lee,
. Under that provision of the Guidelines, a sawed-off shotgun carries a base offense level of 18, whereas other firearms carry a level of 12. U.S.S.G. § 2K2.1(a)(5), (7).
. For instance, in
Melton
we affirmed the district court’s 153 month upward sentencing departure from the applicable maximum 87 month sentence under the Guidelines.
