i have two sti 2011's (double stack 1911) with dawson's supertune package (different than their crp package which is just bolt on parts). supertune is trigger job and reliability work, and some replaced parts. their 9mm sti eagle which i've had for i think 5+ years now has been just about 100% perfect through a bunch of 2 & 3 gun matches, falling steel, some idpa, etc. just bought a 9mm supertuned edge from them.
