Hi there all. I got a Gaucha-IGA 410 single shot shotgun and have a couple of questions. First the gun is marked 3" chamber. I use 3" shells for birds without problems, but I like to carry a box of slugs with me just in case, but they are 2 1/2" long. Would this be o.k. to shoot out of her as a defense round in case I encounter something, or for target? The other question is stupid in my books, but would like to know. A friend recently mentioned that a 45 lc is safe to shoot out of said gun, but I disagree as the round is a lot larger then the bore of my gun. Please tell me I'm not nuts, and that he is wrong.
