Duty Builders Kit
Great kit. Easy assembly. Used a small triangular file to trim the front and rear sights for a snug press fit. The mainspring housing pin was extremely snug. Used sand paper to reduce the diameter. After assembly i found the grip safety is lighter than I expected. I ordered a replacement sear spring from Brownells to tighten up the feel. I will again sand the housing pin to improve the fit allowing for installation and removal without the use of a hammer and punch. Fired 50 rounds no problems reasonable offhand accuracy! Thanks for a great product Bob
