I love my tac 1 fs 45 very accurate! ! I have a tac 2 fs in 40 sw too! But the 45 is more accurate than the tac 2! I'm going to send my tac1 to RIA to get the fo sights installed and the rebuild with wolf springs it will be even more accurate . My eyes see the sights better! RIA 45s are the best bang for your bucks! Better bang than Kimber that's for sure! Price and lifetime warranty and build quality can't be beat! My RIA has never jammed never!
