after buying my first 3 handguns this last year, Berreta Neos, G34 & a G26, I got the bite for a stylish 1911 under 1k. The STI Spartan looks pretty nice and has some features like dovetail target sights that i like. I also hear great things about them from you guys. My question is 1, how easy is it to replace the polymer trigger with the flat trigger myself. 2.) I love the look of a classic A1 spurred hammer, but don't know if a spurred hammer would be an easy addition considering the beaver tail. Thanks guys.
