I've had this Bi-tone 45 tactical since 2008 and I have done some customizing to it, first of I installed a complete Springer trigger kit into it that shortened the reset and take up by half the distance and dropped the trigger pull to 4 pounds, then I installed a solid stainless guide rod, an extended stainless extended ambi magazine catch, a Polly magwell that has held up very good, decal grips, and upgraded the magazines to arradendo 16+1 capacity, and crowned the barrel, just for looks I don't believe it made to much difference to accuracy but every bit helps, this is one bad A$$ pistol, the only thing missing is a set of big dot sights.
shoot safe, shoot straight, and have fun
