My secret weapon. When I want to fool people into believing that I'm a good shooter, I use my STI.
The blueing on the grip wears but so did my Kimber Target. The high cut at the rear of the triggerguard allows a better grip and feels much better than a standard 1911 and the front strap STIppling is comfortable. Mine has the factory skinny grips and that is my preference, I have thin grips on all my guns. The flat top slide is appealing to my eye but I doubt it aids the sight picture.
The mainspring cap and hammer strut are titanium for fast lock times. The firing pin too. The plastic looking graphite trigger glides smoothly in the trigger channel and the trigger pull is 3.25 pounds unmodified but with many rounds through it. I installed a Dawson fiber optic .090" front sight. The narrow width gives me a bit more light gap around the front sight.
I'm now a big STI fan and feel it is one of the best buys on the market.
