The ProMag Magazine for Glock 22, 23, and 27 in .40 S&W is a no-nonsense, high-capacity polymer magazine built for shooters who want more rounds downrange without the constant reload. While the aftermarket magazine world often prioritizes 9mm options, .40 S&W remains a serious choice for defensive and sport shooting—and ProMag stepped up to deliver a solid, affordable alternative when you need extra capacity or just want spares that won't break the bank.
Built from DuPont Zytel polymer, this magazine combines proven durability with consistent reliability. The construction pairs the polymer body with a heat-treated chrome-silicon spring that maintains constant spring pressure through thousands of cycles, so your rounds feed predictably whether you're at the range, in competition, or carrying for defense. Made in the USA and finished in all-black, it integrates cleanly with modern .40 S&W Glocks.
At 27 rounds, you get genuine expanded capacity—a meaningful step up from factory mags—without exotic materials or premium pricing. It's the kind of no-frills upgrade that makes sense if you shoot .40 S&W regularly and want a reliable spare or rotation mag that won't let you down.
