Analysis

This variant applied the Gen4 ergonomic and recoil-management updates to the compact .40 S&W platform, providing a balance of power and concealability in a size comparable to the G19. The dual-spring setup was intended to moderate the recoil impulse of the cartridge while supporting reliable function with a range of .40 S&W loads. The model served as a common choice for law enforcement backup or plainclothes carry and for civilian defensive use, with many examples entering the secondary market through agency trade-ins as departments shifted toward 9 mm.

What can you say 'bout GLOCK that ain't been said already? Fantastic pistol that is as tough as a Sherman tank and very accurate with .40 cal knockdown power. Has been my nightstand handgun for the past half decade. 100% confident that my GLOCK 23 will function each and every time. The G23 is my SHTF pistol, enough said.
