The Tactical II package delivers practical upgrades on a classic 1911 platform. It uses a 5-inch Government-length slide and barrel with a standard barrel bushing and recoil spring plug, keeping the system familiar and serviceable. The single-stack 10mm configuration offers an 8+1 capacity.
The slide and frame are finished in matte black and made from 4140 steel, with a forged slide and cast frame. The frame is non-railed, with a smooth frontstrap and a checkered mainspring housing for a balanced grip profile.
Controls and ergonomics include an ambidextrous thumb safety and a beavertail grip safety with a memory bump. A skeletonized trigger and a skeletonized commander-style hammer round out the Tactical II fire control features. The slide adds rear cocking serrations and a lowered ejection port.
Sights are set up for fast acquisition and fine adjustment: an orange fiber-optic front pairs with a fully adjustable rear featuring two white dots. Gray/black textured G10 grips provide a secure hold.
Markings include "M1911 A1 FS – TACT. II" on the slide, with import and proof marks "APINTL – PAHRUMP NV" and "ACP PHILIPPINES." This configuration aligns with the later Rock Ultra FS naming under item code 51991. Country of origin is the Philippines.
