Value of 7.62 Luger (see pic) form newbie

[Ron Wood]

Fire away Doug, it will work just fine. You can also place a long receiver on a short frame and it will work. It looks funny but it will work. The distance between the takedown lug and the frame stop is identical on both the long frame and short frame, and the receiver lug is the same size and location with respect to the breech on both a long and short receiver. The only difference on the long frame/receiver and the short frame/receiver is forward of the takedown. The receiver travels over the same path and the same distance in recoil and recovery for either configuration.
