No2 MK1 End Shake

Yes, but the case doesn't grip the chamber walls afterwards. It will be driven forward by the firing pin when the pressure falls.

Also note that the rearward motion of the case often partially recocks the hammer, so there's a secondary hit in many cases. Never noticed by the shooter!

( I have a Model 547 S&W that has a case driving pin above the firing pin. The impact of the 9mm case against this pin is sufficient to
drive the hammer to full cock! With the trigger stop i have on this revolver, it would sometimes be fired but the hammer would appear to have never fallen! Weird. But not hard to sort, so now it doesn't do that anymore.)


Breech face of the 547. Note the "case reseating pin" above the firing pin. Needed with the high pressure 9x19 tapered walled cartridge.

Note that if the firing pin hole is too big, there is a small chance that the primer may flow into the clearance enough to lock things up. But I'd guess it's a very remote possiblity with the .380/200 AKA .38 S&W.


BTW, I have some Gun Digests from that period. Any clue which one?
