Just got back from the range. The pistol is very accurate. The problem I am experiencing is with the trigger. Sometimes when I pull the trigger it would not release the hammer to strike the firing pin. I am thinking this is due to the trigger spring. The spring looks out of shape. Does anyone else have any idea what would cause this? I have attached a pic of the spring so you can see what I am talking about. I was using yugo surplus ammo that I got from SOG. Some of these were misfires. I could see that the firing pin dented the primer. Out of 20 shots 6 would not fire. Just a FYI for anyone looking to buy some.
