Description

This is the factory magazine option for Colt's Combat Officer compact-frame 1911 pistols in 9mm. You get 10 rounds of capacity with a stainless steel construction that handles the range environment without worrying about rust or corrosion creeping in over time.

The bumper pad on the baseplate isn't just for looks. It gives you something to grip during reloads, makes the mag easier to seat into the frame, and protects the base from damage if you drop it on hard pavement or concrete. The stainless steel body pairs with precision-engineered feed lips and a quality spring to keep your rounds feeding reliably, round after round.

Because this is a Colt factory magazine, it's specifically dimensioned for the Combat Officer's compact frame. The fit is tight where it matters and indexed properly in the magazine well. If you own one of these pistols, having multiple magazines on hand means more time shooting and less time at the loading bench. Swap between magazines to rotate your stock and let springs relax.

Frequently Asked Questions

Will this magazine fit my Colt Government or Commander model 1911?

No. This is specifically designed for the Colt Combat Officer, which has a compact frame. Government and Commander models use full-size frames and require different magazines that are longer. The Officer frame is shorter overall, so using the wrong magazine can cause feeding issues or fit problems.

Is the bumper pad necessary for my Combat Officer?

The bumper pad serves practical purposes. It makes the magazine easier to grip and extract from the frame with the heel of your hand during reloads, protects the base from impact damage if dropped on concrete, and slightly extends overall length to give you a better grip on the pistol itself. It's not just decorative.

How many of these magazines do I need?

For any semi-automatic pistol, most people recommend having at least two or three spare magazines. Multiple magazines let you practice magazine changes, rotate stock so springs stay fresher longer, and ensure you're never caught with just one mag if something happens to it. Buying a backup or two is smart practice.

Does stainless steel matter for a magazine?

Yes. Stainless steel resists rust and corrosion much better than blued or parkerized steel, especially if you handle the magazine with wet hands, shoot in humid conditions, or store firearms long-term. Since magazines see a lot of hand contact and can spend time on ranges or in gear bags, stainless is a practical choice for durability.

Can I fill this magazine to capacity every time without wearing out the spring?

Magazines naturally lose spring tension over extended periods if constantly loaded to max capacity, especially with the stronger springs required for 10-round magazines. Rotating between multiple magazines and occasionally unloading them to let springs rest extends their lifespan. This is normal magazine maintenance and applies to all high-capacity designs.

What's the difference between this and the standard 6 or 7-round Colt officer magazines?

This 10-round magazine gives you four or three additional rounds of capacity in the same compact frame footprint. Because it's designed specifically for the Officer's proportions, it loads cleanly and feeds reliably without modifying the pistol. The trade-off is slightly more difficult magazine spring loading due to increased tension, but the extra capacity is valuable for personal defense or competition.
