I've had this gun for three years. More or less got it when they came out. Its been my primary waterfowl gun since. I hunt pretty hard usually hunting 2-3 times per week during our season that runs from Sept to January (essentially).
I love Beretta, and I love this gun. I'm not here to B!TCH.
Before I had this one I had a Extrema 2, I also have a Benelli M2 in a 20g, 870's, sp-10 etc. So I'm no newbie, but no expert either. I clean the guns regular and although I hunt hard and don't baby my guns, I wouldn't say I out right abuse them either.
However I've noticed some wear on the A400's bolt. That to me is alarming. Although the gun functions fine, it worries me. On a side note, the A400's are not as reliable as the old A391 actions found in the extrema 2's. At least that's my opinion after having both. However the a400 shoots a lot nicer.
Here are some pix of what I mean.
The first pic shows the wear on the bold "guide pin" from the action slapping the guide pin. I'm not so worried about that.
The second pic shows the pieces of metal missing from the under side of the bolt. This is my major concern.
Also, the chrome is chipping is several area's on the bolt.
Should I be concerned?
Edit: I've never had a 3.5 inch shell issue that others have had. All I shoot is 3.5's from day one. Never had issue's. I've had failures due to not cleaning etc. But not related to 3.5's.
