My CZ 70 hammer drops most all the way before it stops when I let it down with the decocker. I was in the local gun store today and they had a 70 that the decocker would only let the hammer down 1/2 to 3/4 of the way, stopping a good 1/4" before the firing pin. I havn't shot mine yet or to test the decocker with a round in it to see if it will keep from firing. I'm wondering where the hammer stops on most of your CZ 70's and if mine is warn and will fire when decocking? Thanks, rj
