Glock 37 Magazine Features The Glock 37 Magazine is built specifically for that pistol feeding 10 rounds of .45 GAP through the factory magazine well without modification. Manufactured to Glock s exacting tolerances it offers the same fit function and durability shooters expect from a genuine factory part rather than an aftermarket alternative. The black finish matches the factory pistol for a clean consistent appearance whether the magazine is loaded in the gun or carried as a spare. Because it is a factory Glock magazine reliability and drop-free function are built in from the start. Glock recommends a break-in period for new magazines since the last round can be difficult to seat until the spring has compressed somewhat through use. Loading the magazine with all but the last round and letting it sit for a few days or cycling it from full to empty several times helps speed up this process. Once broken in the magazine should feed consistently and reliably through the life of the pistol. This factory Glock 37 magazine is a smart addition for anyone who wants genuine capacity and dependable function.
