Glock 22 Magazines
Factory Glock OEM / KCI / SGM Tactical • .40 S&W • 10 / 15 / 22 / 31 Round
The Glock 22 — introduced 1990 as Glock's first .40 S&W service pistol — was the dominant US law-enforcement duty sidearm from the mid-1990s through the mid-2010s and carried by the FBI as standard-issue 1997 through 2016. Even after the federal return to 9mm, hundreds of thousands of G22s remain in civilian ownership via police trade-in market. Keep Shooting carries the full G22 magazine spectrum: factory Glock OEM 10- / 15- / 22-round, KCI USA factory-equivalent 15-round budget option, and SGM Tactical's 31-round competition extended magazine (cross-compatible with G22, G23, G27, and G35).
About Glock 22 Magazines at Keep Shooting
Keep Shooting carries five magazines for the Glock 22 — factory Glock OEM magazines in 10-round, 15-round, and 22-round capacities, the KCI USA factory- equivalent 15-round budget option, and the SGM Tactical 31-round competition extended magazine. The G22 is Glock's full-size .40 S&W service pistol — the single most-issued US law-enforcement duty pistol of the 1990s and 2000s, still in wide civilian ownership via police trade-in inventory. For the broader Glock magazine lineup, see our parent Glock Magazines category, or the Glock brand page for the full Glock pistol, magazine, and accessory catalog.
The Glock 22 and the .40 S&W cartridge it chambers were introduced in the same year, 1990, and the two products are inseparable in modern American firearms history. The .40 S&W cartridge emerged from the 1986 FBI Miami shootout post-incident analysis, in which the FBI concluded that 9mm Parabellum 115-grain rounds issued at the time had failed to produce immediate incapacitation on two armed suspects during an 8-agent engagement. The FBI's subsequent procurement direction pushed toward the 10mm Auto cartridge (a larger, heavier round) in pistols like the Smith & Wesson 1076, but 10mm's full-power loads proved too punishing in recoil for FBI agents of smaller stature. Smith & Wesson and Winchester then jointly developed the .40 S&W as a reduced- power 10mm derivative — same bullet diameter, shorter case, lower pressure, "FBI Lite" characteristics — released in January 1990. Glock engineered the G22 as the purpose-built service pistol for the new cartridge, launching at SHOT Show 1990 — the first production .40 S&W service pistol and the first .40 S&W Glock.
Between 1990 and 2015, the .40 S&W / G22 combination became the dominant American law-enforcement service cartridge. Adoption reached the FBI (1997, replacing the Sig P226 9mm and S&W 1076 10mm), the DEA, the Secret Service, ICE, dozens of state police agencies, and — at peak — roughly 75% of US municipal law-enforcement agencies that standardized on one pistol. The G22 was the specific sidearm behind most of that adoption. Officers at virtually every US federal law-enforcement agency and the majority of state and municipal police departments carried G22s on duty through the 1990s and 2000s.
The reversal began around 2014–2016. Improved 9mm ammunition (modern bonded hollow-point projectiles) had closed the terminal- ballistics gap that originally justified the move to .40 S&W, while the .40's sharper recoil impulse, faster slide velocity, shorter service-life on duty-use frames, and reduced magazine capacity (15 rounds in .40 vs. 17 in 9mm) created ongoing training and logistics friction. The FBI formally returned to 9mm in 2016, adopting the Glock 17M / 19M, and the subsequent departmental rebuy cycle saw hundreds of federal, state, and municipal agencies follow suit — most shifting to 9mm Glock variants (G17 Gen5, G19 Gen5) or to the Sig M17/M18 (Army MHS winner, 2017). Hundreds of thousands of G22s entered the civilian secondary market through police-trade-in channels during this transition — generally at dramatically discounted prices vs. new retail — and today's G22 civilian ownership base is disproportionately composed of former duty pistols with 10,000–30,000 round service histories.
The G22's dimensions: 7.95 inches long, 5.47 inches tall, 1.26 inches wide, and 25.59 ounces unloaded. Barrel is 4.49 inches. The G22 shares frame dimensions with the G17 service pistol — the .40 S&W conversion is primarily a slide-and-barrel change, with a magazine well geometry adjusted for the fatter .40-caliber cartridge. G22 magazines are specifically designed for the .40 S&W cartridge dimensions and are NOT cross-compatible with 9mm Glock magazines; a 9mm G17 magazine physically fits into a G22 but will not feed reliably. Within the .40 S&W Glock family — G22 (full-size), G23 (compact), G27 (subcompact), and G35 (long-slide competition) — magazines are backward-compatible in the same pattern as the 9mm family: a G22 full-size 15-round magazine will function in a G23, G27, and G35 (with grip protrusion), but G23 13-round and G27 9-round magazines will seat and feed in the larger G22 but offer reduced capacity.
Factory Glock OEM magazines for the G22 come in three configurations. The 15-round magazine ($28.51) is the original service-standard capacity and the magazine shipped with factory G22 pistols since 1990 — steel- reinforced polymer body, stainless spring, polymer follower. The 10-round magazine ($27.19) is the compliance variant for capacity-restricted states — identical construction to the 15-round but with a shortened body and reduced-capacity follower for jurisdictions with 10-round magazine limits. The 22-round magazine ($40.95) is the factory Glock extended magazine — the closest G22 factory analog to the G17 19-round extended magazine — adding seven rounds of capacity via an extended magazine body that protrudes below the grip. This is the factory competition / duty-backup option for shooters who want additional capacity without stepping up to aftermarket extended magazines.
KCI USA's 15-round magazine ($12.99) is the value-priced factory- equivalent option. KCI USA (Korea Precision Industries, imported through KCI USA) produces magazines under military contract for the South Korean Armed Forces and Korean police agencies, including Glock magazines for the K5 service pistol program and the Korean National Police Agency. KCI's civilian-market magazines use the same steel and polymer specifications as the military-contract production — factory-OEM-equivalent at less than half the factory Glock price point. For shooters building up 6–10 magazine inventory for range, training, or reliable duty spares without paying $28 per magazine, KCI is the standard budget-factory alternative. For KCI's broader lineup covering AK, AR-15, M1 Carbine, Mini-14, and other platforms, see our KCI USA brand page.
SGM Tactical's 31-round magazine ($23.69) is the extended-capacity competition and range-practice option for the .40 S&W Glock family. The magazine is cross-compatible across G22, G23, G27, and G35 — every .40-caliber Glock double-stack frame. At 31 rounds, the magazine approximately doubles the G22's factory-standard capacity; the body extends several inches below the grip frame, making it unsuitable for carry but well-suited to 3-gun, USPSA, and steel-challenge competition. SGM is headquartered in Knoxville, Tennessee and is the primary US manufacturer of extended magazines for the Glock service-pistol families. For SGM's broader lineup including Saiga-12 shotgun magazines, Vepr rifle magazines, and AK-47 steel magazines, see our SGM Tactical brand page.
The G22 civilian market today is a distinctive segment. Primary user profiles: former LEO / retired officers who carried the G22 on duty during the platform's peak years and continue to own and carry the pistol they trained on for decades — this is the largest single G22 owner cohort; police-trade-in buyers who purchased duty-retired G22s through trade-in programs at $300–$450 price points vs. $600+ new retail — a value- driven entry-level segment; .40 S&W cartridge loyalists who prefer the cartridge's intermediate recoil / bullet-weight profile over 9mm even after the ballistic rationale has equalized; home-defense users who view the G22 as a proven platform with 30+ years of duty-use validation and a well-developed aftermarket; competition shooters who use the G22 or G35 long-slide variant in USPSA Limited and 3-gun divisions where .40 S&W makes major power factor with less case-capacity effort than 9mm. For all five groups, the magazine ecosystem is mature and well-supported.
Glock (Glock Ges.m.b.H., founded 1963 by Gaston Glock in Deutsch-Wagram, Austria) is the most commercially successful service- pistol manufacturer of the modern era — the 1982 Glock 17 defined the striker- fired polymer service-pistol architecture that now dominates global pistol markets. The G22 represents the peak of that dominance in the .40 S&W era; the platform's continued civilian support — factory magazines still in current production, KCI factory-equivalents, SGM extended magazines — reflects the durability of the installed G22 base even as new-production agency procurement has shifted elsewhere. For the adjacent Glock 26 subcompact 9mm magazine ecosystem that some G22 owners also maintain as off-duty backup, see our Glock 26 Magazines category.
