OK here is a question. I have decided to get another Renington auto. I shot 1100s for several years. In fact I started out with one many moons ago. I am considering an 1187. I have shot the 1187,but, know little about them other than the removable ring that is not on the 1100 and the reciever is not engraved. So how much difference is there? Does the 1187 have the overbore or the standard .727 barrel? Any thoughts?
