My brother bought a brand new Sigma 40 at a gun show yesterday and I took him to the range to shoot. At first it wouldn't fire then for no reason began firing. after about 10 rounds stopped again. It wont click or anything. I'm not an expert but it feels like the trigger needs to be pulled just a little bit more more but it's all the way back. feels like its just on the verge of letting that firing pin go. What do you think? Any tips would be appreciated on what may need adjusted
Sigma 40 won't fire- think it should be easy fix
