Re: Remington 11-87
A couple different types of 11-87's. I would say if it's a "sportsman", stay away, just a cheap version. If it's the "sporting clays" , I had one years ago, ran into a money problem, sold it, regret it to this day. The last version is the "special purpose", I have two of these, one is twenty years old, and my main hunting gun, the other is about 9 years old, and a back up gun.
I shot trap with my original SP for a few years, and I did have some problems with it, but don't really think those guns were made for 100-150 rounds a week. There was no huge problems, piston broke, O-ring here or there, parts were easily ordered direct from Remington, and replaced at home. It's a gas operated gun, so I think that when I put the "shell catcher" on the side, so it wouldn't eject shells out and hit the next shooter over, it may have messed with it somehow, but that's just my thoughts, no one had ever told me that.
Since I bought a trap gun, I don't shoot the 11-87 too much for trap anymore, and just use in hunting situations, and have not had any problems.
