Sig Sauer 1911 Full Size 45ACP 8-Round Magazine

Factory 1911 Magazine

This is a factory Sig Sauer magazine for the full-size 1911 chambered in .45 ACP, holding eight rounds in a single-stack body. It is the right feed source for a Government-size 1911 built to the standard pattern, whether you are replacing a worn magazine or building up a spare set for the range. The stainless body and polymer base pad keep it simple and reliable.

Features

• Eight-Round Capacity — Holds eight rounds of .45 ACP, the standard full-size 1911 load, with numbered witness holes marking counts from 2 through 8.
• .45 ACP Chambering — Built for the .45 Automatic Colt Pistol cartridge, the round the 1911 was originally designed around.
• Full-Size 1911 Fit — Sized for a Government-length 1911 frame, so it seats and locks in any standard full-size 1911 that follows the pattern.
• Stainless Steel Body — The magazine tube is stainless steel, which resists rust and holds up to repeated loading and unloading.
• Numbered Witness Holes — Ports down the side let you see how many rounds are loaded at a glance without pulling the magazine apart.
• Polymer Base Pad — A removable polymer floor plate protects the bottom of the tube and gives you a positive surface to seat the magazine on a reload.
• Factory Sig Sauer Part — Made by Sig Sauer to fit its own 1911 pistols, so you get a known dimension rather than a third-party guess.

Build And Fit

The stainless body pairs with a steel follower and spring and a polymer base pad, the common arrangement on a dependable 1911 magazine. It drops into any standard full-size 1911 in .45 ACP, whether you shoot a Sig or another maker's pistol built to the same spec. Keep several on hand so you can reload quickly at the range and rotate magazines to even out spring wear.
