Glock Magazine for Model 31 .357 Sig — 10 rd

This is a factory Glock handgun magazine manufactured for the Glock Model 31 in .357 Sig. It is a 10-round magazine supplied in black finish and packaged in bulk. The magazine is intended for use as a spare or replacement magazine for compatible Model 31 pistols.

Note: Glock magazines can be 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.
