Warne Glock Magazine Extension Features The Warne magazine extension is built from 6061-T6 aluminum and finished with a hardcoat anodized black coating giving it the durability to hold up against the wear and impact of repeated magazine drops in competition or daily carry. Adding 5 rounds of 9mm Luger or 4 rounds of .40 S&W to compatible Glock 19 and 23 magazines it gives the shooter meaningful additional capacity without switching to a longer magazine body. The finger groove design allows the magazine to be stripped from the handgun more easily when necessary a detail that matters during malfunction clearance or administrative handling. This ergonomic shape also improves the shooter s grip when retrieving the magazine from a belt or pouch under time pressure. Designed and manufactured in the USA the extension reflects Warne s attention to fit and finish on a part that sees constant handling. The stylish black finish keeps the magazine s appearance clean while adding functional value rather than just cosmetic bulk. Competitive shooters in particular benefit from the added capacity and finger groove grip since fewer reloads and faster magazine changes both translate directly into better stage times. For Glock 19 and 23 owners wanting more rounds on tap without a new magazine purchase this extension is a simple proven upgrade for sale at GrabAGun.
