Glock G31 Gen4 Magazine .357 Sig 15-Round

This is a factory original, drop-free magazine for your Glock. 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.

Glock magazines have very stiff springs when new and may be extremely difficult to load to full capacity. It may be necessary to use a Glock magazine loader (generally included in the Glock case with the handgun) to load the magazine to capacity or near capacity.

NOTE: All current production Glock magazines are also compatible with all previous generations of Glock pistols.
