About OA Defense
OA Defense entered the American pistol market focused on a single mission: making the 2011 platform accessible. Previously, 2011-style double-stack 1911-pattern pistols were largely the domain of premium manufacturers commanding $2,000+ price points — primarily Staccato (formerly STI) and custom shop builds. OA Defense's American manufacturing and competitive pricing make the 2011 platform accessible to a broader range of competition and enthusiast shooters without sacrificing quality.
The 2011 Platform
The "2011" is a double-stack evolution of John Browning's classic 1911 design. Same single-action trigger, same grip angle, same thumb safety — but with a wider double-stack frame and magazine that dramatically increases capacity over the traditional single-stack 1911. In 9mm, a 2011 typically holds 17-21 rounds versus 9+1 for a standard 1911. The 2011 dominates USPSA Open and Limited divisions because it combines the 1911's legendary single-action trigger quality with the capacity needed for competition. See our OA Defense 2311 page for full model details.
Why Choose a 2311 Over a Striker-Fired Pistol?
The single-action trigger is the answer. Striker-fired pistols have pre-travel and a longer reset by design — the 2011's single-action trigger has a short, crisp pull with a minimal reset that most competition shooters find produces faster, more accurate rapid-fire splits. For USPSA and similar competition where trigger quality directly impacts score, the 2311's single-action advantage is meaningful. For defensive carry, the 2311's combination of capacity and trigger quality makes it a serious option for shooters already trained on the 1911 manual of arms.
