CZ-83 Safety Mechanisms
« on: August 14, 2015, 04:54:49 PM »
Does the CZ-83 have a firing pin block and a hammer block? Anyone know of a site that lists all of the CZ-83 safety mechanisms?

Thanks

Manual safety, hammer block and inertial hammer. No firing pin block, grip safety, trigger safety, or magazine safety.

I don't know of a site  with an official list, but I believe this is complete.

Thanks for the info. What is "inertial hammer"?

Thanks

The hammer doesn't rest on the firing pin -- there's about an eighth of an inch gap.  When you fire it the hammer's inertia carries it past the gap to hit the pin.

So if you are decocking and you accidentally release the hammer, would it have enough inertia to hit the firing pin?

Yes.  And the slide hurts like hell when you do it, too.  It turns out a better way to lower the hammer is to put your thumb in front of it to block it, pull the trigger, let the hammer go just a fraction forward, release the trigger, and then lower the hammer.  That way if you drop it the hammer block will keep it from hitting the firing pin.

Oops, let me correct myself:  the hammer not resting on the firing pin is called a "rebounding hammer".  I somehow confounded that in my mind with an inertial firing pin, which the CZ also has.  The inertial firing pin is short enough that even with the hammer all the way down, it doesn't contact the cartridge.  The hammer hits it and starts it moving forward; its inertia hits the primer hard enough to set it off.
