Frequently Asked Questions

Will this magazine fit standard 1911 pistols other than Rock Island Armory models?

This magazine is engineered specifically to Armscor and Rock Island Armory specifications for their Ultra 1911 platform in 40 S&W and 10mm. While some standard 1911-pattern pistols chambered in these calibers may accept it, proper fit and function cannot be guaranteed outside of RIA Ultra models. Always verify compatibility with your specific firearm before use.

Is this magazine permanently blocked to 10 rounds, and can the block be removed?

Yes, this magazine is blocked to 10 rounds to comply with California's high-capacity magazine restrictions. It ships in this California-legal configuration from Goodland Guns. Attempting to remove or modify the block to exceed the legal limit may violate California law — always follow all applicable local and state regulations regarding magazine capacity.

How should I store and maintain this steel blued magazine to prevent rust?

Blued steel magazines benefit from periodic light oiling with a quality gun oil or protectant, especially in humid environments. Store the magazine unloaded in a cool, dry location away from moisture. Wipe it down after handling to remove fingerprint oils that can promote surface rust over time. Routine cleaning of the feed lips and interior will also help ensure consistent feeding performance.
