Note:  To modify this magazine for use with .357 SIG 1911s, the magazine's inner rear spacer must be flush or slightly taller than the bottom of the U-shaped tube cut at the top of the tube. This will ensure that the bottleneck .357 rounds do not nose down due to rim drag on the spacer. To adjust the spacer, remove your baseplate and spring/follower assembly and tap the bottom of the inner spacer with a punch towards the u-cutout at the top of the magazine until it is flush.
