Rock Island Armory M1911 A2 Subcompact BBR 3.10 9mm — 3.1 in Ported Bull Barrel, Double-Stack 10+1, Parkerized, Adjustable Sights
The Rock Island Armory M1911 A2 Subcompact BBR 3.10 offers a micro-size, double-stack 1911 in 9mm with an all-steel build and practical features throughout. It pairs a 3.1 inch bushingless, ramped ported bull barrel with a ported slide, matte parkerized finish, and fully adjustable sights. This example comes with three 10-round steel magazines and is in very good condition.
Built on the A2 double-stack frame, the BBR 3.10 delivers 10+1 capacity in a compact footprint. Its dual recoil springs with a full-length guide rod support the short-slide configuration, while the aggressively textured black G10-style grip panels, skeletonized trigger and hammer, and rear cocking serrations round out a purposeful carry package.
Sight picture is fast and tunable, thanks to the orange fiber-optic front blade and a fully adjustable, dovetailed rear marked with R and UP index references. Single-action operation combines a left-side thumb safety and beavertail grip safety for familiar 1911 handling.
This pistol is finished in matte parkerized on both the steel slide and frame. Origin is the Philippines, with proof/import markings APINTL – PAHRUMP NV and ACP PHILIPPINES. Manufacturer part number is 56639, aligning with the BBR 3.10 series designation.
