I can't get my hands on a pm45 were I live and before I order one I would really like to see some comparison pics of the 2 I can't find any on the net.
Just look for a picture comparing J frame to Colt now. Hope this helps.
I have a PM45 and a Colt Officers Model (not the Agent) and I can tell you the PM45 is quite noticably smaller. I carried the OM for nearly 30 years but after getting the PM45 it has been sitting in the bed side drawer.
