The Chip McCormick Power Mag is purpose-built for shooters who want extra capacity without sacrificing reliability in a full-size 1911. This 8-round magazine gives you nine total rounds with one in the chamber, making it a practical choice for range work, competition, or duty use on any Government or Commander model pistol.
The design philosophy here is straightforward: fit more without cutting corners on durability. The all-steel follower design minimizes bearing surface and lets the spring do what it's supposed to do. Unlike traditional designs, this follower actually works as part of the spring system, allowing Chip McCormick to use larger, higher-tensile coils than you'll find in other extended magazines. The result is a magazine that handles the brutal feeding cycle of the .45 ACP consistently, whether you're shooting brand new ammo or running through a box of older stock.
The stainless steel body with laser-welded tube handles corrosion and abuse. Numbered witness holes let you visually count rounds without opening the mag, and the removable polymer base pad makes field cleaning easy when you need it. Black fluoropolymer finish delivers a clean look that works with any pistol.
These magazines are known for working reliably across different 1911 brands and models. They seat fully loaded without excessive binding, and that all-steel construction means the magazine can handle getting beat up at the range or in daily carry without developing the feeding issues that sometimes plague lower-quality extended mags.
Yes, this Power Mag is designed specifically for full-size Government and Commander model 1911 pistols. It'll fit flush and seat properly when fully loaded. If you've got a compact or officer-sized 1911, you'd need the compact version instead.
You get nine total rounds with one in the chamber, plus better feeding reliability. The all-steel follower and larger spring coils work together to handle the demanding cycle of the .45 ACP more consistently than magazines that just squeeze eight rounds into a seven-round design.
These are designed to load fully with the slide in battery without excessive binding. Some 1911 models may require slightly more pressure than others, but that's normal and not a sign of a problem. If you're having real difficulty, check that your magazine is actually designed to hold eight rounds.
Chip McCormick magazines are built to handle thousands of load and unload cycles. The high-tensile Rocket Wire spring is one of the toughest on the market. Eventually all magazine springs wear out from heavy use, but these give significantly longer service life than budget alternatives.
Power Mags have a solid reputation for feeding reliably across various 1911 manufacturers, from Colts and Springfields to aftermarket builds. They're versatile enough that many folks with multiple 1911s just buy Chip McCormick mags for all of them.
The black fluoropolymer finish over the stainless steel body gives you the durability of stainless with a cleaner appearance. The stainless steel underneath still provides excellent corrosion resistance if the finish gets scratched during use.
