The ejector on our STI Duty One, left, was much longer than those found on either the Kimber, right, or Springfield Armory pistol, center.
After suffering malfunctions, we returned our Duty One to STI for warranty service.
The STI Recoil Master is a multi-spring, plunger-style recoil system that reminded us of a shock absorber found in a racing car. The accessory rail was one feature that adds to its value as a tactical weapon.
The horizontal lines machined into the Heinie brand sights were very effective in absorbing glare. The sight picture was excellent.
