Glock .40 refers to Glock pistols chambered in .40 S&W (e.g., G22 full-size, G23 compact, G27 subcompact). They’re known for reliability, duty use, and strong terminal performance. Works with model/Gen-specific parts: .40 S&W slides, barrels (standard or threaded, commonly 9/16×24), recoil spring assemblies, frames, trigger kits/connectors, pins/springs, sights, and .40 magazines. Compatible accessories include weapon lights, optics (MOS/plates), compensators, and suppressors (threaded barrel with appropriate piston/booster). 9mm conversion barrels and mags can enable caliber conversion on some models.
