Glock 43 Magazine Features This Glock factory magazine is purpose built for the Glock 43 holding 6 rounds of 9mm Luger in a compact polymer body reinforced with a hardened steel core. That steel core keeps the feed lips true and the magazine body rigid through repeated loading and firing cycles a durability advantage over lower-cost aftermarket alternatives. The included extension adds extra room for the shooter s little finger improving grip and control without significantly increasing the pistol s overall footprint. Because it is a genuine Glock factory part it is machined to the exact specifications the Glock 43 was designed around for dependable feeding. New Glock magazines can be difficult to load to full capacity right out of the box so Glock recommends a break-in period before relying on it for daily carry or competition. Loading the magazine with all but the last round and letting it sit for a few days helps compress the spring and cycling it from full to empty several times speeds up that break-in process. Keeping a genuine factory spare on hand ensures a reliable backup for concealed carry range practice or duty use. This Glock factory magazine for the Glock 43 is available for sale at GrabAGun for shooters who want a trusted factory-correct spare magazine.
