The Match Grade 1911 magazine from CMC is a traditional USGI-style fixed base magazine with improvements in follower design, feed lip geometry, and materials. Its die-controlled tolerances are held to +/- .001 which is more than 75% tighter than magazines made to typical military specifications. Springs are made from aerospace-grade rocket wire and large viewing holes are numbered to quickly determine round count at a glance. The stainless steel Match Grade features a welded base plate for the ultimate in durability, drilled for base pad. (sold separately)
