Glock G21 .45 ACP 13 Round Pistol Magazine Black 1 Pack 13

Glock G21 .45 ACP 13 Round Pistol Magazine Black 1 Pack 13. Factory Glock magazines have a hardened steel insert encased in high tech polymer. This polymer coating protects the magazine and prevents deformation even when dropped from a great height. Note: Glock magazines can be very difficult to load when new. Often the last round will not fit until the magazine has undergone a break-in period. It is recommended that the magazine be loaded with all but the last round and left for a few days to compress the spring. Cycling the magazine from full to empty multiple times can assist in the break-in period.
