The Springfield 1911 TRP AOS pistol in .45 ACP with a classic black finish and 4.25-inch barrel (brand part no. PC9124LRCCAOS) equips the compact Tactical Response Pistol with the Agency Optic System for direct red dot mounting. Springfield Armory pairs the optic-ready, serrated slide with tritium front and black serrated rear sights for co-witnessing with an installed optic, and 1-in-16 rifling twist supports consistent accuracy. An ambidextrous thumb safety accommodates both hand orientations, and the pistol ships with three magazines. Among compact optic-ready semi-auto handguns, this 1911 TRP AOS configuration favors carry shooters who want red dot flexibility in a shorter package.
