The Rock Island 1029RW is the factory Armscor magazine for the Rock Warrior and BBR 3.10 pistols chambered in .45 ACP. It holds 10 rounds in a double-stack configuration, which is a big part of what makes these compact sub-compact 1911s so appealing in the first place. You're getting full-power .45 ACP capacity in a package that would normally cap out at 7 or 8 rounds in a single-stack setup.
Construction is steel throughout the body with a blued finish for corrosion resistance and that classic 1911 look. The follower and base plate are polymer, keeping things light where it counts without cutting corners on the structural components. Because this is a genuine Armscor OEM part, it's made to the same manufacturing specifications and tolerances as the magazine that shipped with your pistol. That means proper fit, reliable feeding, and no guesswork about aftermarket compatibility.
This is the kind of magazine you grab when you want a spare that just works. Whether you're training at the range, stocking up after wearing out your original, or simply want a backup ready to go, the 1029RW is the right call for Rock Warrior and BBR 3.10 owners. No modifications, no fitment issues, no drama.
Yes, the 1029RW is compatible with both the Rock Island Rock Warrior and the BBR 3.10 pistol. These two platforms share the same double-stack .45 ACP magazine design, so the 1029RW fits and feeds correctly in both. This is the same magazine that ships with the BBR 3.10 from the factory.
This is a genuine OEM Armscor magazine, manufactured to the same specs and tolerances as the original equipment mag that comes with your Rock Island pistol. It's not a third-party knockoff. If you want the most reliable drop-in fit, sticking with the factory mag is always the safest bet.
The Rock Warrior and BBR 3.10 are built on a widened double-stack frame inspired by the Para Ordnance Warthog platform, not a traditional single-stack 1911 frame. That wider grip allows the double-stack magazine to fit, which is how you get 10 rounds of .45 ACP in a sub-compact package. A standard single-stack 1911 magazine will not fit this pistol.
No. The Rock Warrior and BBR 3.10 use a proprietary double-stack magazine design specific to their wider frame. Standard single-stack 1911 magazines are not compatible. You need the 1029RW or a magazine specifically designed for this platform.
The magazine body is steel with a blued finish. The follower and base plate are polymer. This matches the construction of the original factory magazine and provides a solid balance of durability and reliability.
For a range session with a compact pistol like the BBR 3.10 or Rock Warrior, most people find that two to three magazines keeps things moving without a lot of downtime reloading. Having at least one spare beyond your carry mag is a smart move, both for range efficiency and as a backup in case one magazine eventually wears out or gets damaged.
