I sent my MA1 subframe and striker parts to bigtaco. A week later, I had a 1911 quality trigger in my Steyr. There is the normal take up pf spring compression necessary for this type of trigger, and then...a nice, clean SNICK. Really an excellent trigger break. I've function fired about 150 rounds and it is flawless. I'll shoot it in next competition I get to. Excellent work, thanks BT.
