Just acquired a 1930 Commercial C96 Mauser pistol in a good 98% condition and have been researching everything from history and variations to safety and takedown (field strip) procedures. Field stripping begins with the pressing in of the Magazine Floor Plate Release pin enough to slide the Floor Plate forward and off the Magazine Housing itself. Easy enough. However, my Floor Plate won't budge! The release pin is depressed enough to free the Floor Plate, but it won't slide forward at all. Now be advised the fit of the Floor Plate is tightly toleranced. Looks to be every bit the fit of a S&W revo side plate. Obviously, I don't want to "force" it. I tried some Kroil, let it soak where the Floor Plate and Magazine Well meet. Still no luck. Any ideas, guys? Thanks for your help.
