The Rock Island Armory BBR 3.10 is a compact .45 ACP pistol built for shooters who need serious stopping power in a small package. At just 3.1 inches of barrel length and weighing in as one of the lightest .45 ACP options on the market, this single-stack delivers full-caliber performance without the bulk of a full-size service pistol. The 10+1 round capacity gives you meaningful firepower for self-defense or close-quarters work, while the parkerized finish protects against corrosion in the field and at the range.
The BBR 3.10 is designed to be carried and shot, not admired from a safe. Snag-free combat sights—fiber optic front and adjustable MPS2 rear—get you on target fast in low-light conditions. The G10 grip panels provide a secure, no-slip purchase even when your hands are stressed, cold, or wet. A beavertail grip safety ensures the gun sits high in your hand for better recoil control and faster follow-up shots, crucial when you're working with .45 ACP's substantial kick in a compact frame.
Whether you're building a deep-carry backup gun, want a truck gun that won't weigh down your seat, or need a no-nonsense home-defense pistol, the Rock Island Armory BBR 3.10 delivers the terminal authority of .45 ACP without compromise. At this price point, you're getting a purpose-built tool from a brand with real production chops, not a budget shortcut.

Yes. At 3.1 inches of barrel length and described as one of the lightest .45 ACP pistols in its class, the BBR 3.10 is sized for deep carry or truck-gun roles where compact dimensions matter. The snag-free sights and parkerized finish are purpose-built for that mission.
The gun is outfitted with a fiber optic front sight (dovetail-mounted) and an adjustable MPS2 rear sight. Both are combat-oriented and designed to minimize snags during holster draw.
The trigger pull ranges from 5 to 7 pounds, typical for a .45 ACP single-action platform.
The pistol carries 10 rounds in the magazine plus 1 in the chamber for a total capacity of 10+1.
