Greetings all. I'm a new forum member (just joined). Got myself a CZ75B and a 2075B for Christmas! Love them!
While I initially wanted to get a BD myself, I got tired of waiting and got the model with a manual safety. In retrospect, I actually prefer it.
Anyway, in regards to safely decocking, I trained myself the two hand method. Hold your gun in the right hand (duh). Cover the firing ping with your left thumb. Hold the hammer with your right thumb. Now, quickly toggle the trigger. By that I mean, pull it so the hammer releases and immediately let go, moving index finger back on the side of the frame. Now that the hammer is free, and your finger is off the trigger again, you can either a) remove your left thumb and lower the hammer with right thumb into the decock position, or b) lower the hammer onto your left thumb, then remove your left thumb. (the former would be preferred).
Since you have the firing pin covered with your left thumb during the trigger pull, which is the only time the firing pin block is disengaged, there should be zero chance of an accidental discharge. In essence, your left thumb acts as a firing pin block during that brief moment the internal firing block is removed when the trigger is all the way back. I find this method very safe. Just make sure you train yourself to perform these three steps with deliberately. Thumb over FP, trigger pull AND release, thumb removal.
If you are ever in a situation where you only have one hand available, simply engage the safety, and once you have your left hand available again, then decock.
Hope everyone had a great Christmas!
Cheers,
Frank
