Factory magazines are the simplest reliability upgrade for any 1911, and this is a genuine Colt seven-round .45 ACP magazine cut for the shorter Defender and Officer's Model frames. Compact 1911s are far more sensitive to magazine quality than full-size guns because of their shorter slide travel and stiffer recoil springs, so running correct-length factory mags matters.

Stainless construction resists corrosion during carry, and it comes packaged for retail. Keeping several on hand also lets you rotate springs before they take a set.
