My Pops has one that we got from wally world, it has had a ton of FTE problems and FTFs. He brought it to me at Christmass and I tried to clean it up good and ran some 3 inch threw it and it still jamed twice on a 25 round box. I wasnt reall happy with it.
If you are dead set on the 1187 I would get a used one you know runs right. I ended up getting a Mosberg 930 and LOVE it.
