ILANA DIAMOND ROVNER, Circuit Judge.
Terry L. Wilson was a minor at the time he committed the crime of dehvering a controlled substance. The government moved to transfer him to adult status pursuant to 18 U.S.C. § 5032, and after a hearing, the dis *611 trict court granted the motion. Wilson subsequently pled guilty, reserving his right to challenge the transfer ruling. He now claims three errors in the district court’s ruling. First, he faults the court for considering the fact that he possessed a firearm during the distribution, arguing that the court may not consider uncharged conduct in assessing the nature of the alleged offense. Second, he argues that the district court exceeded its authority when it considered his entire juvenile record instead of confining its review to convictions. Third, he charges that the district court abused its discretion in finding that the interest of justice was served by transferring him to adult status. Because we find that the district court acted well within its discretion, we affirm.
I.
At the age of sixteen, Wilson was charged in a juvenile complaint with three counts of distributing cocaine and one count of distributing crack. If committed by an adult, these offenses would constitute violations of 21 U.S.C. § 841. On one occasion when he was delivering drugs to a government informant, Wilson invited the informant into his bedroom to show off his 9 mm. semiautomatic pistol. Wilson indicated to the informant his willingness to use the gun, and demonstrated its operation. Wilson then completed the transaction by supplying the informant with an ounce of cocaine in exchange for cash. The record does not reveal whether Wilson possessed or brandished a gun in relation to any other drug transaction.
On the government’s motion to transfer Wilson to adult status, the district court held a hearing and then granted the motion. Pursuant to § 5032, the district court considered six factors in determining whether a transfer to adult status would be in the interest of justice, and made findings on the record with respect to each one: (1) the age and social background of the juvenile; (2) the nature of the alleged offense; (3) the extent and nature of the juvenile’s prior delinquency record; (4) the juvenile’s present intellectual development and psychological maturity; (5) the nature of past treatment efforts and the juvenile’s response to such efforts; and (6) the availability of programs designed to treat the juvenile’s behavioral problems. At the further direction of the statute, the court considered “the extent to which the juvenile played a leadership role in an organization, or otherwise influenced other persons to take part in criminal activities, involving the use or distribution of controlled substances or firearms.” 18 U.S.C. § 5032.
The district court found that Wilson had a very troubled social history'and came from a very unstable home environment. In weighing whether these findings favored transfer, the court opined that Wilson’s age and social history “cut both ways.”
United States v. TLW,
For the second factor, the court contemplated the scope of evidence it could consider in determining the nature of the alleged offense. Relying on
In re Sealed Case,
In weighing Wilson’s juvenile record, the court determined that it could properly consider the entire delinquency record, and not just the convictions, as Wilson urged.

We review § 5032 transfers for abuse of discretion.
United States v. Jarrett,
A.
Wilson relies entirely on
Sealed Case
for the proposition that the district court may not look beyond the allegations contained in the indictment when assessing the nature of the .alleged offense.
Here, the district court considered that Wilson possessed and brandished a gun during the delivery of cocaine to a government informant. Although the indictment did not mention the gun, we believe the district court was correct to consider it in evaluating the nature of the alleged offense. The gun was not, after all, unrelated to the offense, but was used by Wilson to help facilitate the cocaine delivery. In that sense, the firearm possession was neither “discrete” nor “independent” but rather part of the offense, and *613 spoke to the gravity of the offense. Wilson could have delivered cocaine and crack without brandishing a firearm in the process, but he increased the risk of violence by introducing the gun into the transaction. Congress did not limit the court’s review to the facts alleged on the face of the indictment, but instead used a much more expansive phrase, the “nature of the alleged offense.”
Our conclusion is bolstered by the sentencing guideline applicable to Wilson’s offense. Section 2D1.1 of the Guidelines specifies the base offense level for trafficking in drugs. Part (b) of that Guideline addresses “Specific Offense Characteristics,” the first of which is relevant here: “If a dangerous weapon (including a firearm) was possessed, increase by 2 levels.” That the Guidelines consider possession of a firearm to be a “specific offense characteristic” of trafficking in drugs supports a finding that gun possession goes to the nature of the alleged offense of distributing cocaine. In fact, the district court applied that very enhancement to Wilson’s sentence, and he did not object. Wilson thus tacitly admits that possession of the gun could be considered an integral part of the offense. The district court was therefore correct to consider Wilson’s firearm possession in assessing the nature of the alleged offense.
B.
Wilson next complains that the district court erred when it considered his entire juvenile record, including a number of arrests that did not result in convictions. As with the “nature of the alleged offense” provision, we are confronted with a paucity of case law interpreting this part of the transfer statute. The government cites
United States v. Parker,
We agree with the district court. The plain language of the statute directs the court to consider “the extent and nature of the juvenile’s prior delinquency record.” 18 U.S.C. § 5032. Again, Congress could have limited the inquiry to the juvenile’s prior convictions, but it did not. Instead, the statute allows review of the delinquency record, which includes arrests as well as convictions. We agree with the district court that the government should not be allowed to hold mini-trials, attempting to prove the underlying conduct in those instances where an arrest did not result in a conviction. Such evidence is outside the juvenile’s record and thus is not within the limits contemplated by the statute. Moreover, these collateral proceedings would greatly burden the parties and the court with no discernable benefit. The district court struck the proper balance in reviewing the juvenile delinquency record in its entirety and nothing else. Ultimately, the district court found that Wilson’s juvenile record weighed in favor of transfer, and we have no reason to find that the district court abused its discretion in making that finding. At the tender age of sixteen, Wilson’s record already spanned seven years and evidenced an alarming propensity towards violence. The court was well within its discretion to find that such a record favored transfer to adult status.
C.
Wilson also faults the district court for placing excessive emphasis on the nature of the alleged offense when concluding that the transfer would be in the interest of justice. Wilson advocates equal consideration of each of the six factors set out in § 5032, and argues that transfer would be inappropriate when only one factor weighs in favor of transfer, three weigh against, and two cut
*614
both ways. A number of circuits have held that, although the district court must consider all six factors, it need not give equal weight to each, but may balance them as it deems appropriate.
See United States v. Juvenile JG,
We join those circuits today and hold that the district court had discretion to give more weight to some factors than to others. Determining whether the transfer of a juvenile to adult status is in the interest of justice is not a simple arithmetical exercise, where the court adds up all the factors to see if the sum is a positive or negative number. The district court was within its discretion to give more weight to the nature of the alleged offense than to the other factors.
