Thanks for the replies everyone. I'm at work at the moment but when I get a chance I'll take a look to see if it's #67. In any event I will probably end up taking this back to the shop and let them take a look at it. Of course it could also be any of the parts that Tucker301 mentioned!
Rest assured I certainly won't shoot it until I'm happy that the gun is servicable. When done I need to take this to the local range and shoot some. It would be tragic if I take it on a hunting trip and it lets me down, especially as I'm a novice hunter.
One thing concerns me is that I do store this with barrel removed butt plate down. The shotgun with it's long barrel is simply to long to easily fit in my gun safe.. so I have to. Is there anything I need to be careful of when doing this to make sure parts don't fall out?
I actually have an R-870 tactical 18" that I have as a home defense weapon and I'm very happy with it. I was all fired up to get another 870 for hunting but my very experienced hunting friend convinced me that the Benelli Nova is super reliable and the best for the money option as a hunting shotgun. We're not off to a good start with bit's dropping out of it! :-( I hope this is just teething problems.
Thanks!
