I have inherited a cmp mp45 semi pistol, the same as an encom mark 4 I have been told. HOWEVER, it was only partially assembled and no matter how I try I end up with two small machined parts that I can't seem to get it right. Ideally I would like a schematic or a dissembly-assembly manual or SOMETHING, ANYTHING that can help me get this thing operational so I can try it out by shooting it in a remote Arizona desert area. I will gladly pay for help, am not a cheap person, and appreciate any man's time, respecting his help in any fashion. My direct email is "email@example.com" God bless you all and my country of America.
