ProMag PM050 Floor Platemade of Polymer with Black Finish & Extra Gripping Surface for Glock Mags 2 Per Pack (Adds 2rds 9mm Luger, 1rd 40 S&W)

The ProMag PM050 polymer floor plate is a simple, non-permanent way to boost magazine capacity on your Glock 9mm or .40 S&W pistols. These injection-molded basepads slip onto your factory Glock magazines—9mm gets an extra two rounds, .40 S&W gains one—without any permanent modification or gunsmithing. If you're running a defensive or duty gun and want a few more rounds on tap without swapping mags, or just want the flexibility to upgrade existing magazines, this 2-pack gives you the parts to modify two separate magazines.

Beyond the capacity bump, the floor plate design includes an extended grip surface. More material to purchase means a better purchase point when you're manipulating the magazine during reload drills or tactical transitions. The grip texture helps when you're working wet, gloved, or in the dark. It's a small detail that adds up during repetitive practice.

ProMag engineered these to fit standard Glock factory magazines—no special models or proprietary hardware required. The black polymer construction resists corrosion and won't snag on gear or holsters. Drop them on your existing mags and you're done; if you ever want to go back to factory specs, removal is just as easy.
