Trigger Problem
I have a Mossberg 500. When i have a shell in it and squeeze the trigger it doesn't go off the first time. It might take 2 or 3 squeezes till it fires. If i put a shell that has been already fired in it, it will fire everytime. Also, if i dry fire it, it will fire everytime. So i'm not sure when it will go off. It's a pump if that helps any. Can anyone give me some advice before i take it to the gunsmith?
