When you own an Auto-Ordnance 1911, having a backup magazine on hand just makes sense. The G21B is the standard factory magazine for full-size Auto-Ordnance 1911 pistols chambered in .45 ACP, holding 7 rounds in a single-stack configuration. It is built to the same manufacturing specifications and tolerances as the magazine that came in the box with your pistol, so fit and function are consistent right out of the packaging.
The body is all steel with a corrosion-resistant blued finish that matches the classic look of the Auto-Ordnance 1911. Inside, a high-tensile music wire spring provides firm, consistent feed pressure and helps ensure positive slide lock on the last round. The low-friction, controlled-tilt steel follower keeps rounds aligned for smooth feeding without binding. Numbered witness holes run along the side so you can do a quick round count without dropping the mag.
The floor plate on this model is welded in place and non-removable, which keeps things simple and structurally solid. There is no disassembly needed or intended. It is a drop-in, grab-and-go magazine built for reliability.
This one is worth picking up in multiples if you shoot your Auto-Ordnance 1911 with any regularity. Rotating through a few magazines is always better than running the same one to death, and having a spare ready during a range session keeps things moving. It also ships as the included magazine with certain Auto-Ordnance 1911PKZ model configurations, which speaks to its role as the genuine factory option rather than an aftermarket substitute.
This magazine is designed specifically for full-size Auto-Ordnance 1911 pistols chambered in .45 ACP. Per the manufacturer, it is made to fit Auto-Ordnance firearms produced in Worcester, MA and Greeley, PA. While the 1911 platform is fairly standardized, Auto-Ordnance recommends sticking with their factory magazines for the most consistent fit and reliability.
No. The G21B uses a welded, non-removable floor plate, so it is not designed to be disassembled. If you prefer a magazine you can field strip for deep cleaning, the Auto-Ordnance 1911 Commander version with a removable baseplate is worth looking at instead.
Yes. The G21B is the standard magazine included with certain Auto-Ordnance 1911PKZ model configurations, and it is manufactured to the same specifications as those original equipment magazines. That means you are getting a genuine factory replacement, not an aftermarket approximation.
The G21B holds 7 rounds of .45 ACP in a single-stack configuration, which is the traditional capacity for a full-size Government-pattern 1911 magazine. It is not compatible with 9mm or any other caliber.
The 1911 platform is fairly standardized, and many owners find that this magazine feeds reliably in other full-size 1911 pistols as well. That said, some 1911s are particular about tolerances, so your best bet is always to test any new magazine before relying on it.
Yes. The magazine features numbered witness holes along the body so you can get a quick visual round count without dropping the mag. It is a small detail but genuinely useful at the range or in any situation where you need to check your load fast.
