Out of battery safety?

So was I right ? if I understood you correctly , this cam is in actuality does sound like an out of battery safety? Not just to pull the striker back?(which seems redundant, because, the whole bolt travels back carrying the striker and than leaves it behind hanging on a sear while returning to battery.

Erma 22 kit does exactly that, no cam, and the striker can hit the primer prematurely, but it,s not a disaster for a simple blowback with puny 22.

While the cam/ firing pin relationship during normal operation is as I said, pay attention to what Dwight also says if the firing pin is cocked and the action doesn't fully close. Squeezing the trigger to release the firing pin with the action not fully closed will allow the action to slam closed with the firing pin following and possibly contacting the primer with enough force to ignite it. Look at the picture below. At that point, the firing pin has engaged the sear and is cocked. On most Lugers, the toggles will remain that way until the trigger is squeezed. (A weak firing pin spring can allow the action to close as the recoil spring applies pressure) Squeezing the trigger will release the firing pin and the action will slam shut. NEVER do that with a cartridge in the gun. To store a Luger - unloaded, of course - with the firing pin at rest, break the action as shown and grip the toggles while squeezing the trigger. EASE the action closed.

Got it. Thanks. Appreciate the points.
