Description
This polymer magazine pairs with the Advantage Arms 1911 conversion system to deliver affordable range training on your existing 1911 platform. Built from impact-resistant polymer with a reinforced steel spring, it holds 10 rounds and delivers consistent feeding performance through rigorous training sessions.
The stand-out feature here is the last-round hold open. That steel insert lets the slide lock back when the magazine runs dry, giving you immediate visual confirmation that you're out of ammo. No more guessing or accidental trigger pulls on empty chambers. It's a detail that matters when you're running drills.
Polymer Construction Built for Training
Weight matters when you're swapping between your duty gun and a conversion setup. At around 1.9 ounces, this magazine won't bog down your training day, and the polymer body handles the wear that comes with regular use. The flat polymer follower combined with that steel spring means smooth, reliable feeding whether you're running CCI, Federal, or other standard velocity loads through your setup.
Purpose-Built for 1911 Conversions
This magazine is engineered to work with the Advantage Arms 1911 conversion kit only. It won't fit or function in your standard 1911 centerfire magazines, and your original 1911 magazines won't work with the conversion system. When you're setting up your conversion kit, grab one or more of these to round out your magazine collection for practice days. The 10-round capacity keeps you in the action longer between reloads.

Frequently Asked Questions
Will this magazine work with my standard 1911 or other conversion kits?
No, this magazine is designed exclusively for Advantage Arms 1911 .22 LR conversion kits. It won't fit standard 1911 centerfire magazines or work with conversion systems from other manufacturers. Compatibility is limited to the Advantage Arms platform only.
What's the last-round hold open feature and why does it matter?
The last-round hold open is a patented design feature that locks the slide back when you fire the final round in the magazine. This gives you instant visual feedback that you're empty, which is especially useful during training drills and practice sessions where you want to know immediately when it's time to reload.
Can I use this magazine with different brands of .22 LR ammunition?
Yes, this magazine functions well with most standard velocity .22 LR ammunition including CCI, Federal, and Remington brands. The steel spring and flat polymer follower provide consistent feeding across different loads, though standard velocity rounds are recommended for best results with the conversion system.
Do I need a conversion kit to use this magazine?
Yes, this magazine requires the Advantage Arms 1911 conversion slide kit to function. The magazine alone won't convert your 1911 to .22 LR. You'll need to swap your standard slide for the Advantage Arms conversion slide and use this dedicated magazine to complete the setup.
