1. CZ says you can do that but doesn’t recommend it. The latest versions of the CZ75 platform now come with a decocker.
2. If you’re going to do that, you can do what most of the CZ owners who do the same thing say they do on their forums - convert to SAO because they also see the DA part as useless in that case.
And up until recently anyways, Colt's Series 80 and 90 pistol manuals stated, "ALWAYS KEEP AND CARRY YOUR PISTOL EMPTY, WITH THE HAMMER FORWARD EXCEPT WHEN YOU INTEND TO SHOOT."
In fact, a quick look online at your Springfield XD manual also says, "Always keep and carry your firearm with an empty chamber until you intend to shoot..."
Do you carry yours with nothing in the chamber?
