Ed Brown's Special Forces SR pistol is built for pure performance and extreme use. It starts with a government model frame with integral light rail, and adds a fully blended magwell for a smooth fit and quick magazine changes. Ready for use with a suppressor, the threaded barrel is standard on this model. The slide features front and rear cocking serrations and is complete with a Trijicon RMR (Ruggedized Miniature Reflex) sight, which is the most rugged miniature red dot sight available, and has the versatility to be used in any lighting condition. Trijicon tall iron night sights complete the sight set up, providing the perfect backup sight system. A unique and highly durable Chainlink III pattern provides a secure grip for severe applications. Whether you're shooting for pleasure, or for tactical use, the Special Forces SR has everything you need for serious performance in a dedicated suppressor 1911 pistol.
