Just don’t trust the decocking function, and get a couple of spare firing pins. I don’t leave a round chambered at all, safety or not. It is so easy to work the slide that I just leave it empty. And get some Serbian “Golden Bear” hollow points. They expanded in my basic “shoot into sand” tests to the same .50 cal diameter as my 9mm hps.
Ammo is a little scarce right now, but I ferret some out. I can’t believe what a great gun I got for a mere pittance.
