Built on STI’s 2011 modular double-stack architecture, this Tactical 4.0 pairs a steel frame and polymer grip module to deliver .45 ACP capacity with a compact footprint. The slide is marked "TACTICAL 4.0" and wears both forward and rear cocking serrations for positive manipulation.
The 4.6-inch threaded barrel with a knurled thread protector is a notable feature on this variant, complementing the full-length dustcover and integral multi-slot accessory rail. Sighting is iron-only with a dovetailed front blade and a Heinie-marked rear.
Controls include a single-action-only fire control system with a frame-mounted thumb safety and a grip safety. A skeletonized rowel hammer and a flat-faced, skeletonized, red anodized trigger are installed, providing a modern 2011 control layout.
The pistol ships with five magazines (three 15-round and two 12-round), giving a 15+1 on-board capacity when using the 15s. The installed hand-stippled polymer 2011 grip module enhances purchase, and the original STI grip module and original trigger are included for those who prefer factory configuration.
Pre-Staccato STI markings include the Texas-outline logo and "STI International – Georgetown, TX USA," reflecting its U.S. manufacture. The threaded-muzzle Tactical 4.0 configuration is less common relative to the cataloged non-threaded spec, adding interest for buyers seeking this specific setup.
