Description
The Kimber 1911 .22 LR polymer magazine delivers the performance you need for plinking, training, or just putting rounds downrange without breaking the bank on ammunition. Built to factory specifications, this 10-round magazine fits full-size Kimber rimfire pistols and their conversion kits, giving you a dedicated mag that works with what you've already got.
Construction and Reliability The entire mag is polymer except for the high-quality steel spring and follower, which keeps weight down while maintaining the durability needed for regular range use. That steel spring paired with the polymer follower works together to ensure smooth, reliable feeding so you can focus on your groupings instead of troubleshooting jams. The lightweight polymer body means carrying multiple mags won't bog down your range bag.
Practical Features for Range Use Every mag includes a witness window on the side so you can glance down and see how many rounds you have left without breaking your grip or slowing down your shooting. The flush-fit floor plate gives it that clean 1911 look while keeping everything compact. It feeds just like a centerfire mag, so if you're coming off your standard 1911, the transition feels natural.
Knowing Your Compatibility This magazine works with Kimber Rimfire Super pistols, Rimfire Target pistols, and the standard .22 LR Rimfire Conversion Kit. It does not work with Kimber's blue-cased Platinum conversion kit, so double-check your setup before ordering. If you're running the right platform, this is the no-fuss replacement or spare mag you need.

Frequently Asked Questions
Will this magazine work with my 1911 rimfire conversion kit?
Yes, if you have Kimber's standard .22 LR Rimfire Conversion Kit. This magazine is specifically designed for Kimber rimfire platforms. However, it will not work with Kimber's blue-cased Platinum conversion kit, so verify which one you own before ordering.
How reliable is the polymer construction compared to a steel magazine?
The polymer body combined with the steel spring and follower has a solid track record for reliability in Kimber rimfire setups. The polymer keeps weight down without sacrificing feeding performance, and the steel internals handle the spring tension and follower wear that take the most abuse.
Can I load this magazine to full capacity?
Yes, the magazine holds a full 10 rounds. You can load it completely if you prefer, though some users load to 7 or 8 rounds to match centerfire 1911 mag capacity out of habit. Either way works fine.
What makes the witness window useful?
The witness window lets you quickly check your remaining round count without removing the magazine from your grip or slowing down at the range. Just glance down and you know if you need a reload.
