Promag Handgun Magazine Black for Glock 43x/48 9mm Luger 20/rd

The Promag Handgun Magazine Black for Glock 43X/48 9mm Luger with 20-round capacity delivers extended firepower in a compact platform without requiring modifications to your pistol. This magazine seamlessly integrates with Glock 43X and Glock 48 platforms, providing operators and shooters with a significant capacity boost while maintaining drop-free compatibility with factory mag catches.

Construction centers on a heat-treated steel body with black oxide finish, engineered for durability during repeated loading cycles and corrosive environments. The magazine incorporates a polymer catch insert that allows use with standard Glock mag catch hardware—no gunsmithing or aftermarket parts needed to achieve reliable function. The injection-molded follower and heat-treated chrome silicon spring ensure consistent feeding geometry across the 20-round stack, critical for reliable performance during high-round-count training sessions or duty use.

This magazine serves shooters seeking extended capacity in the Glock 43X and 48 platforms—subcompact 9mm pistols valued for their concealability. The 20-round option provides substantially more ammunition on board than factory single-stack 10-round magazines while accepting a slightly longer profile. Users conducting defensive training, range practice, or casual marksmanship benefit from the reduced magazine changes and faster engagement cycles. Manufactured in the USA, the Promag magazine delivers proven reliability for both recreational and professional applications.
