Rock Island BBR 3.10 .45 ACP | 3.1 in | 10+1 | 51577

The Rock Island Armory BBR Series 3.10 is a compact .45 ACP 1911-style pistol built for shooters who want maximum cartridge performance in a smaller package. It ships with G10 grips, a black parkerized finish, and a 3.1-inch barrel with a 1:16″ twist. For a compact pistol like this, a small footprint red-dot such as a Holosun 507C pairs well and stays well under $1,000 while improving sight acquisition for close-range work.

Appropriate real-world uses include concealed carry where legal and short-range target or utility shooting at the range.
