Got a chance to buy a MK4BR (?) it think. it's a MKII 4" bull barrell with very nice walnut grips. I didn't want to handle it much because it might not let me go. It is one very nice gun. Looks unfired, and I believe it's from the mid-90's. The LGS wants $346 but may negotiate. I don't know these guns at all but understand they may be a limited run? Not made anymore in this configeration? It has box, manual and fired case so it is LNIB. What's your feedback?
