Frequently Asked Questions

Will this magazine fit my standard single-stack 1911?

No — this ACT-MAG is specifically engineered for the Armscor and Rock Island Armory A-2 double-stack 1911 platform chambered in .45 ACP. Its wider double-stack body will not fit or function correctly in a standard single-stack 1911 frame. If you're unsure whether your pistol is a double-stack model, check your owner's manual or the model designation on your frame.

Why does a 13-round body only hold 10 rounds in California?

California law restricts detachable magazine capacity to a maximum of 10 rounds. This magazine uses a full 13-round double-stack steel body for structural integrity and proper feeding geometry, but it is blocked and certified to hold no more than 10 rounds, making it fully compliant for purchase and use in California. The 13-round body designation refers to the physical size of the magazine shell, not the legal capacity.

How should I store and maintain this steel magazine?

To keep your ACT-MAG in peak condition, store it unloaded in a cool, dry environment away from moisture, which can cause rust on the blued steel body. Periodically wipe the exterior with a light coat of gun oil and inspect the feed lips and spring for wear or deformation. Disassembly is straightforward — simply remove the polymer base plate, slide out the spring and follower, and wipe clean before reassembly. Avoid storing magazines fully loaded for extended periods to preserve spring tension over time.
