ZEV +5 Basepad for Glock 17 Magazine - Gray

The ZEV +5 Basepad for Glock 17 Magazine is a straightforward capacity upgrade for shooters who want more rounds between reloads without buying new magazines. This gray aluminum basepad simply replaces the factory floor plate on your standard 17-round Glock 9mm or .40 S&W magazine, adding five extra rounds to 9mm mags or four to .40 caliber—a practical boost for range days, competition, or defensive carry. ZEV Technologies engineered it as a 3-piece design that comes apart and reassembles cleanly, so you can maintain and clean your magazine without fuss.

Installation is dead simple: remove the factory basepad, slide the ZEV basepad into place, and you're done. No special tools or gunsmithing required. The included enhanced magazine spring is rated for the increased capacity, so your rounds feed reliably at full load. The whole package is lightweight—you won't notice the difference in your mag pouch—and built tough enough to handle the demands of regular shooting. It's the kind of upgrade that pays for itself the first time you avoid a mag change on the clock.

This basepad is designed specifically for 17-round Glock magazines only; it won't fit compact or subcompact mags. If you're running standard-capacity double-stack Glock 9mm or .40 pistols, this is a no-fuss way to squeeze more firepower into the same footprint. Note: ZEV does not ship these to California residents due to state regulations.
