I have had mine for a little over a year now and it is the best gun I have ever shot.I have put about 2000 rounds threw mine { give or take a few } and not one problem. I have had it in a down pour duck hunting and in dusty conditions upland bird hunting and have not had one mis fire or any sore shoulders.
I used 3.5 for a long time but nw I only use 3in and knock down just as many birds if not more because I don't start regret pulling the trigger like I did with 3.5s.
