Sig Sauer 1911 Government/Commander .45 ACP 8-Round Stainless Steel Magazine

The Sig Sauer 1911 Government/Commander .45 ACP 8-round stainless steel magazine is built for shooters who demand reliability in their handgun's most critical component. Whether you're running a Government-frame or Commander-frame 1911, this factory magazine delivers consistent, trouble-free feeding with the kind of construction quality you expect from a top-tier firearms manufacturer. Stainless steel construction resists corrosion and wear, so your mags stay functional whether they're seeing range time, home defense duty, or riding in a carry rig.

Sig Sauer magazines have earned their reputation through decades of service in professional hands—military, law enforcement, and civilian shooters alike trust them. That track record matters: a magazine failure in a defensive situation isn't just an inconvenience, it's a liability. This one-piece stainless design is engineered to handle full-power .45 ACP loads without babying, and the 8-round capacity balances firepower with the controllable ergonomics that make 1911s what they are.

If you own a full-size Government or compact Commander-frame 1911 in .45 ACP, keep at least one spare magazine on hand—and this is the OEM choice that fits and feeds as designed. Stainless construction means minimal maintenance and long service life, even if a mag spends more time loaded than in active use.

Frequently Asked Questions

Will this magazine fit my Sig Sauer 1911?

Yes—this magazine is designed for Sig Sauer 1911 Government (full-size) and Commander (compact) models. Verify your frame size before ordering. Other 1911 brands may or may not be compatible; this is engineered for Sig frames.

What's included in the box?

You receive one 8-round stainless steel magazine. Followers, springs, and base pads are factory components; no additional parts are bundled separately.

How many rounds does it hold?

8 rounds of .45 ACP ammunition.

Why stainless steel over blued or parkerized?

Stainless steel resists rust and corrosion far better than blued finishes, especially in humid or wet environments. For a magazine that may sit loaded for extended periods or see variable storage conditions, stainless offers lower maintenance and longer reliable service life.
