I just put a new Ed Brown Magwell on my 1911. After that, the 1911 will fire with the grip saftey disengaged ( no pressure on it what so ever ) and the thumb safety disengaged.The thumb safety still works fine, the weapon will not fire with it engaged.I put the mainspring back in properly.I just bought the 1911 today. Gun Show in town this weekend, or I can take it to my Dept. Armorer. I think the sear spring could be bent any ideas????????
