Hammer down, intertial firing pin.
You can't get it to fire that way. Slam the hammer with a mallet on a loaded chamber, hammer down.You aren't going to make the hammer hit the firing pin fast enough to force the inertial firing pin forward into the primer. Just not going to happen. It requires a full force hammer strike to ignite primers. Hammer down, the hammer is resting on the firing pin, but it's not able to make it touch the primer.
You guys need to look at your guns closely. A CZ-75B or Pre-B model doesn't have a firing pin long enough to contact the hammer and firing pin at the same time. It's designed to be struck by the hammer and travel forward into the primer, but only when the spring is overcome by the inertia of the strike. The hammer resting on the pin can't make the gun fire unless it is struck with enough force to move the pin past the breech face and into the primer. Have you played croquet? You use a big mallet to strike a big ball which is touching another big ball. Now, add a spring and a very low mass firing pin to this mix. Not going to move far, and not with much force.
Hammer down is totally safe. Cocked and locked is totally safe. The only problem I can think of is Half-cock, which is potentially more dangerous, because the hammer spring might be just strong enough to ignite the primer if the sear trips. The safety isn't engaged in half-cock, so the danger increases, slightly.
