The SP01 Tactical has the decocker. I prefer the safety. Its not going to be a carry gun (too big) but it should kick ass at the range or the bedside.
It’s a nice feature to have if for some reason your hands are shaking and you don’t trust yourself to drop the hammer manually.
Have it on the P-O1, but just a safety on the .45.
The nice thing about a big pistol like the SP or 97 is it feels so solid, less felt recoil.
Downside, it’s a little heavy compared to a striker pistol.
But you’re really going to like the CZ quality, fit and finish!
