I like it! Can't wait to shoot it. Everything looks OK. However, I bought a second mag and will have to send it back to CDNN. It won't lock in like the mag that came with the shotgun. One snaps in and the other won't. You may think it is seated but if you tug on it, it comes out of the mag well. I'm going to get a slip-on buttpad extension from Wally world for it and put a buffer in it. Where do I get a buffer for this puppy? Also, it came with the 0.0 cylinder choke. Is this the equivalent to a full choke? (Sorry if this is a stupid ?) I read owner's manual but don't see offhand h
