Remington 11-87. Had it since '89. Put a **** ton of shells through it in the last 20 years...dove, turkey, deer, rabbit, snakes, rats, clays, etc. Probably my most sentimental gun due to all the trips I've taken with it.
I have a Mossberg 500 A 12 gauge that can take a serious ass whipping and keep right on going. As a matter of fact I had a game time injury last dove season - a little cardboard and duct tape and it was dropping dove left and right.
