In this single-issue sentencing appeal, the government implores us to set aside defendant-appellee Erie Gray Snyder’s sentence. The district court predicated that sentence on a disparity between the sentence mandated for the offense of conviction by the federal sentencing guidelines and the sentence Snyder likely would have received had state authorities prosecuted him.
See United States v. Snyder,
I. BACKGROUND
We touch lightly upon the facts of the ease as they are only obliquely relevant to the legal problem that this appeal presents. On January 10, 1995, a known drug user, John Hawk, told a Boston police officer, William Doogan, that Snyder had robbed him and his paramour at gunpoint and stolen a number of Valium tablets. Hawk further stated that Snyder, driving a black Honda and accompanied by Frank Diaferio (a reputed drug dealer known to Dоogan), was headed toward Roslindale. Doogan knew that Diaferio resided at 17 Murray Hill Road in Roslindale and he immediately arranged for police surveillance of that locus. When Snyder and Diaferio arrived in the black Honda, the officers found a loaded .32 caliber pistol in a locked briefcase in the car’s trunk. Doogan placed Snyder under arrest. During a search at the station house, police officers recovered 26 Valium tablets from Snyder’s pants pocket.
Initially, Massachusetts authorities charged Snyder under Mass. Gen. L. ch. 269, § 10(a) (1990) with unlawfully carrying a firearm, an offense punishable by a 2½-to-5-year prison term. When a federal grand jury later returned an indictment that charged Snyder with being a felon in possession of a firearm in violаtion of 18 U.S.C. §/ 922(g)(1) (1994), Massachusetts dropped the state charge.
In due course, a federal trial jury found Snyder guilty. The probation office thereafter prepared a presentenee investigation report (the PSI Report). The PSI Report indicated that Snyder’s extensive criminal history rendered him subject to the sentencing enhancement provisions of the Armed Career Criminal Act, 18 U.S.C. § 924(e) (1994) (ACCA). Employing the corresponding sentencing guideline, USSG § 4B1.4 (Nov.1995), the PSI Report projected the guideline sentencing range (GSR) to be 262 to 327 months.
Judge Harrington conducted a three-day sentencing proceeding. On October 9, 1996, Snyder’s counsel arid the prosecutor sparred over Snyder’s insistence- that he was not subject to the ACCA because certain of his prior convictions did not qualify as predicate offenses thereunder. See 18 U.S.C. § 921(a)(20) (1994) (delineating various exclusions from the taxonomy of eligible- predicate offenses). In the course of that hearing, Judge Harrington expressed reservations about the steepness of the projected sentencing range. Afterwards, he issued a memorandum that noted his “grave concern” with the “gross disparity” between the GSR and the punishment that Snyder would have rеceived had state authorities pursued and obtained a conviction on the originally charged state offense. In that memorandum, the judge made no bones about his disdain for “the unfettered and unreviewable discretion of the United States Attorney” to prosecute in federal court the “ ‘local’ offense of carrying a firearm.” He concluded by scheduling a further hearing to address the issues “whether this disparity in sentences and the de facto selective prosecution of the defendant raise any constitutional concerns and whether the combination of the above two issues justify [sic] a downward departure under USSG § 5K2.0.”
At the resumed hearing, held on December 12, 1996, Judge Harrington reiterated his belief that sentencing Snyder to a 21-year prison term would cоnstitute a “gross violation of the principles of justice.” Engaging in what some might consider wishful thinking, the judge then predicted the demise of the sentencing guidelines:
*67 I said yesterday to the U.S. Attorney’s Office, this type of de facto, selective prosecution continues. And when there is a disparity of over 20 years for the same offense, .., the guidelines are going to be dismantled becausе the federal judiciary will no longer, no longer put up with it. It’s going to be dismantled.
Judge Harrington convened the third, and final, sentencing session on January 14,1997. He ruled that Snyder fell within the ambit of the ACCA and that USSG § 4B1.4 therefore applied. He computed the GSR to be 285 to 293 months.

Judge Harrington then departed downward pursuant to USSG § 5K2.0 and sentenced Snyder to an incarcerative term of 180 months (the mandatory minimum under the ACCA). He premised the departure squarely on the ground that the federal/state sentencing disparity created by interleaved federal and state criminal jurisdiction over Snyder’s conduct “is contrary to the very objective of and theory upon which the Guidelines are grounded and therefore takes this case out of the heartland and makes it atypical.”

II. STANDARD OF REVIEW
We deal here only with the government’s sentencing appeal.
3
We review a district court’s decision to depart from the guideline sentencing range for abuse of discretion.
See Koon v. United States,
Whether the guidelines countеnance a particular ground for departure is a question of law.
See Koon,
*68 III. ANALYSIS
We turn now to the validity of the district court’s stated ground for departure. Thе twin stanchions on which our analytic framework rests are the generic departure guideline, USSG § 5K2.0 (a guideline that flows directly from the congressional command embodied in 18 U.S.C. § 3553(b) (1994)) and the Court’s opinion in Koon.
Section 5K2.0 permits a sentencing court to deviate from the range indicated by an otherwise applicable guideline computation if it finds “that therfe exists an aggravating or mitigаting circumstance of a kind, or to a degree, not adequately taken into consideration by the Sentencing Commission.” In considering whether an appropriate “aggravating or mitigating circumstance” exists, the court first must ask “[w]hat features of th[e] case, potentially, take it outside the Guidelines’ ‘heartland’ and make of it a special, or unusual, ease[.]”
Koon,
In mounting this inquiry, we do not write on a pristine page. Although the Sentencing Commission does not expressly proscribe federal/state sentencing disparity departures, five federal appellate courts have taken the measure of such departures. All have held that federal/state sentencing disparity is never a valid basis for a downward departure.
See United States v. Searcy,
Snyder harps on two facts: most of these decisions predate Koon,
4
and federal judges are less free under the
Koon
regime to exorcise specific factors from the departure calculus.
See Koon,
The letter of the sentencing guidelines is unhelpful in this instance. Departures based on federal/state sentencing disparity are not expressly permitted or forbidden in the guidelines’ text, nor are they explicitly encouraged or discouraged. As a result, we must mull the “structure and theory of both relevant individual guidelines and the Guidelines taken as a whole,”
Koon,
The Commission’s enabling statute directs it to “establish sentencing policies and practices for the Federal criminal justice system that ... avoid[ ] unwarranted sentencing disparities among defendants with similar records who have been found guilty of similar criminal conduct____” 28 U.S.C. § 991(b)(1)(B) (1994);
see also
USSG Ch.1,
*69
Pt.A, intro, comment. 3. The legislative history makes it crystal clear that Congress’s allusion to “unwarranted sentеncing disparities” reflected a concern with variations among federal courts across the nation, without reference to their state counterparts.
See United States v. Aguilar-Pena, 887
F.2d 347, 351-52 (1st Cir.1989). In terms, then, the guidelines seek to promote uniform sentencing among federal courts in respect to federal crimes.
See Deitz,
The trial judge sought to elongate this principle, speculating that “it would only be logiсal that Congress would not favor disparity throughout the criminal justice system in an era of increased Federal-State cooperation in the investigation and prosecution of crime.”
Snyder,
If the guidelines’ gоal is to promote uniformity among federal courts when imposing sentences for federal crimes, then departures aimed at alleviating federal/state sentencing disparity are flatly incompatible with it. Endeavoring to make a federal sentence more closely approximate that which a state court might impose for similar criminal activity would reсreate the location-based sentencing swings that Congress sought to minimize when it opted for a guideline paradigm.

See Searcy,
The short of it is that the guidelines did not sprout in a vacuum. Congress and the Sentencing Commission erected the рresent sentencing structure against the skyline of an extant criminal justice system,
see Haynes,
We add, moreover, that disparity between federal and state sentences in career offender cases is hardly serendipitous. Congress crafted thе ACCA on the central premise that armed career criminals were being treated too gently by state courts — coddled, some might say — and that these defendants ought to receive much stiffer sentences.
See United States v. Jackson,
*70
We are equally unimpressed with the district court’s attempt to hang its finding of atypicality on an aversion to federal prosecutors’ discretionary power to target defendants under federal law.
See Snyder,
For these reasons, we hold that federal/state sentencing disparity is not a feature that can justify a departure. Such departures would contradict hopelessly the guidelines’ structure and theory as well as impinge impermissibly upоn the Executive Branch’s discretion to prosecute defendants under federal law.
See Dockery,
We add a coda. The continuing federalization of criminal law increases the frequency with which federal/state sentencing disparities occur,
see generally
Steven D. Clymer,
Unequal Justice: The Federalization of Criminal Law,
70 S. Cal. L.Rev. 643 (1997), and we are not entirely unsympathetic to Judge Harrington’s concerns about this trend. Still, judicial dissatisfaction with a particular аspect of the guidelines, “no matter how steeped in real-world wisdom, cannot be enough to trigger departures.”
Aguilar-Pena,
IV. CONCLUSION
In sum, federal/state sentencing disparity is not “a mitigating circumstance of a kind, or to a degree, not аdequately taken into consideration by the Sentencing Commission in formulating the guidelines that should result in a sentence different from that described.” 18 U.S.C. § 3553(b). Hence, we vacate Snyder’s sentence and remand for resentencing.
We close by addressing one further point. In our companion opinion,
see supra
note 3, we approved for the time being the district court’s adherence tо
United States v. Estrella,
Vacated and remanded.
Notes
. The difference between the GSR projected in the PSI Report and that actually used stemmed from Judge Harrington’s finding — not contested on appeal — that the government had not proven that Snyder, committed an armed robbery. This finding shrunk Snyder's base offensе level from 34 to 33, see USSG § 4B1.4(b)(3)(B), and effected a commensurate decrease in the GSR.
. On appeal, Snyder attempts to divert our attention to alternative rationales that arguably support the downward departure. But Judge Harrington’s decision makes no mention of such factors. To the contrary, he expressly stated that ”[t]o this Court the issue raised is ... one of disparity between the sentences to be imposed.”
Snyder,
.Snyder appealed his conviction and his classification as an armed career criminal. We heretofore affirmed his conviction.
See United States v. Snyder,
No. 97-1187,
. The lone exception is Searcy, a case decided after this case was briefed and argued.
. One Commission member illustrated the swings that occurrеd in the pre-guidelines era by recounting the following findings:
The region in which the defendant is convicted is likely to change the length of time served from approximately six months more if one is sentenced in the South to twelve months less if one is sentenced in central California.... [B]lack [bank robbery] defendants convicted ... in the South are likely to actually serve approximatеly thirteen months longer than similarly situated bank robbers convicted ... in other regions.
Hearings on Sentencing Guidelines Before the Subcomm. on Criminal Justice of the House Comm, on the Judiciary, 100th Cong., 1st Sess. 554, 676-77 (1987) (testimony of Commissioner llene H. Nagel).
. We think it unremarkable that the Commission has not expressly forbidden federal/state disparity departures. Given that the guidelines were never intended to fostеr parity between federal and state defendants, Commission commentary on the subject would be supererogatory.
. We find no record evidence of an unconstitutional exercise of prosecutorial authority in this case. We note, moreover, that Judge Harrington himself ruled in an unpublished order dated December 27, 1997, that Snyder had failed to make out a prima facie case of selective prosecution.
