Can anybody explain the difference between a MKII and a MKIII?
I think the differences are that the Mark III has a loaded chanber indicator, an internal safety lock, and will not fire with the magazine out of the gun.
I stripped my new gun prior to firing and the hinged pin was very tight but I got it out with a wooden dowel and a pecking hammer. After working with it a few times it loosened up a little. I could not get the barrel off the frame, at least not by applying an amount of force I thought safe without risking damage, so I just left it on and went shooting. A few hundred rounds should loosen things up.
I have learned the value of "RTFM" through dealling with these guns.
