The Springfield Armory 1911 TRP AOS in .45 ACP, with a 4.25-inch barrel and a black finish, is the shortened, carry-minded Tactical Response Pistol (brand part no. PC9124LR-CCAOS). A lightweight forged aluminum Carry Contour frame with a bobbed rear portion keeps the grip comfortable while cutting down on printing under a cover garment. The slide is cut for the Agency Optic System, so a red dot mounts directly, and a tritium front sight with a black serrated rear sight stays usable behind it. Twenty line-per-inch checkering and top slide serrations carry over from the full-size TRP. It suits a shooter who wants a carry 1911 that takes a red dot without a custom slide cut, from Springfield Armory.

Key Specifications

• The chambering is .45 ACP, the traditional 1911 cartridge.
• The barrel is a 4.25-inch hammer-forged stainless steel match-grade barrel, which holds accuracy and resists wear.
• Rifling twist is 1:16, matched to standard loads for this chambering.
• Each pistol ships with three 7-round magazines, so spares are ready for the range.
• The slide is optic ready through the Agency Optic System, with plates for popular footprints such as RMR, Shield, Delta Point Pro and Docter.
• The sights are a tritium front with a black serrated rear, and the AOS plate carries the rear sight so the irons co-witness in most setups.
• The slide is forged carbon steel with Black Cerakote and top serrations that reduce glare and speed up sight alignment.
• The frame is forged aluminum alloy with the Carry Contour, which trims weight and softens the heel of the grip so the pistol conceals better.
• Grips are VZ Grips Hydra G-10 with 20 line-per-inch checkering, a texture that stays secure when hands are wet.
• Recoil is managed by a Commander-length GI-style recoil system sized to the 4.25-inch slide, which suits this barrel length.
