About Glock Magazines at Keep Shooting
Keep Shooting carries the complete Glock magazine universe — 80+ SKUs spanning every Glock pistol platform ever produced, every cartridge Glock has chambered in four decades of continuous production, every capacity from the 6-round Slimline G42 flush-fit through the KCI 50-round drum, and every factory finish from Gen5 black through FDE and Olive Drab. This is the parent hub for our five dedicated subcategory pages — Glock 17, Glock 19, Glock 22, Glock 26, and Glock 42 — plus standalone SKUs for every other Glock platform. For the complete Glock pistol, magazine, and accessory catalog, see our Glock brand page.
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 won the Austrian Army service-pistol competition — the first polymer-framed striker-fired pistol to enter serious military service — and redefined the global service-pistol market. Today Glock produces over 20 pistol models chambered in seven cartridges across five generations of engineering evolution, with an installed base of 20 million-plus pistols worldwide and dominant market share across US federal law enforcement (65%+), state and municipal police, US Special Operations personal-purchase sidearms, civilian concealed carry, and export-contract national military service. The magazine ecosystem — factory OEM plus a deep, mature aftermarket — is the most developed pistol-magazine market in the world.
Cartridge-by-cartridge, the Glock platform universe.
9mm Parabellum — Glock's dominant chambering and the largest magazine ecosystem at Keep Shooting. Covers the G17 (full-size service, 1982), G18 (full-auto machine pistol, 1986 — civilian not legal but magazine fits G17), G19 (compact, 1988), G26 (subcompact, 1995), G34 (long-slide competition, 1998), G43 (Slimline single-stack subcompact, 2015), G43X (Slimline full-grip, 2019), G45 (full-size grip + compact slide hybrid, 2018), and G47 (CBP-contract variant, 2019). Double-stack 9mm magazines (G17, G19, G26, G34, G45, G47) are mutually cross-compatible — the shorter-frame mag in the larger pistol seats flush with reduced capacity; the larger-frame mag in the smaller pistol protrudes below the grip with full capacity. The Slimline single-stack family (G43, G43X) uses entirely different magazine geometry and is NOT cross-compatible with the double-stack family. See our Glock 17 Magazines (22 SKUs), Glock 19 Magazines (17 SKUs), and Glock 26 Magazines (13 SKUs) for the double-stack subcategory pages. G43 and G43X Slimline magazines are stocked as standalone SKUs including factory OEM, factory-with-grip-extension, ETS 7-round, and G43X 10-round factory magazines.
.40 S&W — the cartridge that dominated American law enforcement from the mid-1990s through the mid-2010s. Covers the G22 (full-size service, 1990 — FBI standard issue 1997–2016), G23 (compact, 1990), G27 (subcompact, 1995), and G35 (long-slide competition, 1998). All four .40-caliber Glocks share a common double-stack magazine family — a G22 full-size 15-round magazine fits and feeds in the G23, G27, and G35; a G23 13-round magazine fits and feeds in the G22 and G35 (with reduced capacity); a G27 9-round subcompact mag fits in all four platforms. Keep Shooting carries factory Glock OEM magazines for all four pistol platforms plus KCI factory- equivalent 15- and 13-round magazines and SGM Tactical's 31-round extended competition magazine. See our dedicated Glock 22 Magazines subcategory (5 SKUs).
.45 ACP — Glock's entry into the classic American .45 cartridge began in 1990 with the G21 (full-size service, 13-round capacity), joined by the G30 subcompact in 1997 (9-round and 10-round capacities), and the discontinued G36 single-stack variant (2000, Glock's only single-stack .45 ACP before the Slimline family). Keep Shooting carries factory Glock OEM 10-round and 13-round G21 magazines, 9-round and 10-round G30 magazines, G36 single-stack magazines for the discontinued platform (secondary-market support), and SGM Tactical's 26-round extended .45 ACP magazine for competition and range use across the G21 family.
10mm Auto — Glock launched the .40 S&W era by first embracing the full-power 10mm Auto cartridge in the G20 (full-size service, 1990) and G29 (subcompact, 1997). Both platforms were designed around the original FBI-specification 10mm load before the FBI downshifted to the lower-pressure .40 S&W. The 10mm Glocks became enthusiast favorites for Alaskan bear defense, hunting, and full-power-cartridge concealed-carry; both platforms remain in current Glock production. Keep Shooting carries factory OEM 15-round G20 magazines and 10-round G29 magazines.
.380 ACP — Glock's Slimline platform launched in 2014 with the G42, Glock's first single-stack subcompact and first .380 ACP — designed specifically for US pocket-carry market entry and manufactured in Smyrna, Georgia to bypass GCA 1968 import restrictions on small- frame foreign-made handguns. 6-round flush-fit and extended-grip factory magazines plus ETS translucent 9- and 12-round extended options. See our dedicated Glock 42 Magazines subcategory (5 SKUs).
.45 GAP (Glock Auto Pistol) — Glock's only proprietary cartridge development, introduced 2003. The .45 GAP was engineered to deliver .45 ACP-class terminal ballistics from a cartridge short enough to fit in the 9mm-frame pistol chassis, allowing the G37 (full-size, 2003), G38 (compact, 2005), and G39 (subcompact, 2005) to offer .45-class performance in a smaller grip frame than the G21/G30. The .45 GAP never achieved commercial traction — adopted by a handful of state police agencies (Georgia State Patrol, New York State Police, South Carolina Highway Patrol among them) but rejected by the civilian market in favor of .40 S&W and modern 9mm — and Glock quietly discontinued the G37 family from catalog production by 2019. Keep Shooting stocks factory G37 magazines for the installed .45 GAP ownership base — secondary-market support for an orphaned platform.
.22 Long Rifle — the newest Glock chambering. The G44 (2020) is a dedicated .22 LR rimfire training pistol built on the G19 frame dimensions — the identical manual of arms, identical trigger feel, identical sight picture as a full-size 9mm G19, but with cents-per- round rimfire ammunition economics that transform range-practice costs. The G44 is a dominant training-pistol platform for serious G19-owner practice routines. Keep Shooting carries factory 10-round G44 magazines.
Aftermarket manufacturer ecosystem. The Glock magazine aftermarket is the most developed in the US pistol market. Primary manufacturers represented in Keep Shooting's catalog: Glock OEM (factory production from Deutsch-Wagram, Austria and Smyrna, Georgia — the definitive reference magazine for every platform); Magpul (Cheyenne, Wyoming — PMAG GL9 family, polymer body with stippled exterior and anti-tilt follower, the leading polymer-first aftermarket choice); ETS (Elite Tactical Systems) (Sevierville, Tennessee — translucent polymer magazines showing round count at a glance, extended 22-round G17 and 12-round G42 options); KCI USA (factory OEM for the Korean K5 service pistol — the widely-recommended budget factory- equivalent including 50-round drum — see our KCI USA brand page); Hexmag (Mansfield, Ohio — hexagonal-surface carbon-fiber-reinforced polymer, PMAG-style AR-market pedigree); UTG / Leapers Inc. (Livonia, Michigan — value-priced training magazine tier at $9.97–$19.97); Amend2 (Rexburg, Idaho — polymer magazines at roughly 50% of factory Glock OEM pricing); and SGM Tactical (Knoxville, Tennessee — steel-and-polymer extended competition magazines, 31-round .40 S&W and 33-round 9mm variants — see our SGM Tactical brand page).
Choosing a Glock magazine — buying framework. For daily concealed carry: factory Glock OEM or KCI factory- equivalent. For duty / defensive use: factory Glock OEM Gen5 (current spec with auto-slide-lock support). For range training: UTG or Amend2 at the budget tier, Magpul PMAG or Hexmag at the mid-tier, factory Glock OEM at the premium tier. For competition: factory Glock 24-round / 33-round extended, SGM 31- or 33-round extended, or the full-auto-heritage Glock 18 18-round ETS variant. For maximum capacity / range-toy: the KCI 50-round drum. For capacity-restricted states: 10-round factory magazines (all major manufacturers produce 10-round compliance variants). For factory-finish color coordination: factory Glock OEM in FDE or Olive Drab matches to FDE or OD pistol configurations.
