I have started to keep an empty casing in the chamber of my lugers but I have an Arty (1917) that is a really nice gun in all respects; but an empty casing in it is hard to close up and then it is nearly impossible to open back up again. I have to take the top off and open up the gun to get the casing out. I don't have this problem with any other of my lugers. What might this be a sign of? Haven't tried live ammo as I don't like having a cartridge lodged in a chamber.
thanks
Jack
