Hello, I am new to the forum & have a question that I cannot find an answer to. Maybe I'm just not using the correct nomenclature, I don't know. My question is in regard to re-assembly. I just got done re-assembling a Series 80 Colt Government model 1911. I took my time with it, double, triple checked & made sure everything was put back correctly, by the book. I installed a new mainspring, magazine spring, a heavier firing pin spring & 16.5 recoil spring. I safety checked it in every manner possible & it performs without fault. My issue comes into play when I rack the slide, without my finger on the trigger, sometimes the hammer drops & it seems almost random. Sometimes the hammer drops & sometimes it doesn't, though I feel like it drops when I really try & let it rip. I tried doing it without my palm on the grip safety, but can't seem to replicate it. Any help would be greatly appreciated. Thank you in advance.
