Advantage Arms 22 LR Magazines: The Key to Reliable Training
The Advantage Arms Conversion Kit is the gold standard for rimfire training on a centerfire frame. However, the kit is only as reliable as its fuel source. Advantage Arms 22 LR Magazines are precision-engineered to provide the same “Glock-like” reliability you expect, featuring a crucial last-round hold open that maintains the muscle memory of your duty or carry sidearm.
As of 2026, Advantage Arms has expanded their lineup to include extended high-capacity magazines, allowing for longer training strings and more efficient range sessions.
Why Stick to Advantage Arms Factory Magazines?
While aftermarket “grey-market” mags exist, Advantage Arms factory magazines are required for the system to function correctly.
-
Last-Round Hold Open: Unlike many rimfire conversions, these magazines are designed to lock the slide back on the last shot, signaling an empty chamber just like your 9mm or .45 ACP setup.
-
Steel-Reinforced Feed Lips: To prevent the common “nose-diving” issues associated with .22 LR, these magazines utilize hardened polymer and reinforced geometries to ensure consistent feeding.
-
Caliber-Specific Design: These are not modified 9mm mags; they are ground-up .22 LR designs built to fit perfectly into your standard Glock or 1911 frame.

Pro-Tip: The “Golden Rule” of 22 LR Reliability
Advantage Arms conversion kits are precision machines. To ensure 100% feeding reliability with your magazines, we (and the manufacturer) strictly recommend using high-velocity, plated round-nose ammunition.
-
Recommended: CCI Mini-Mag 40gr RN (The gold standard for these magazines).
-
Avoid: Cheap bulk-pack lead “bucket” ammo, which can lead to lead buildup on the feed lips and stovepiping.
Save Money, Shoot More
In the current economy, 9mm and .45 ACP costs can hinder frequent training. By switching to the Advantage Arms system, you can shoot 500 rounds of .22 LR for the price of one box of premium centerfire ammo. These magazines allow you to keep your trigger press, grip, and holster draw consistent without breaking the bank.
