I'm with bigwheelzip. For self defense/carry use, I'd prefer the decocker version.
To me, the only reason to get the safety version is because you want to carry cocked-and-locked, like a 1911 or Hi-Power (full mag, round in chamber, hammer cocked, safety engaged). I've owned 1911s and I can't recall ever failing to disengage the safety, but I've never had to do it with the stress of someone trying to kill me. Lots of people have successfully defended themselves with a cocked-and-locked gun so it is a viable option if that's what you prefer and are willing and able to train with it that way.
I prefer to be able to simply draw and pull the trigger if I need to shoot under stress. I also like the heavier, longer DA trigger for a bigger margin-for-error in terms of safe handling, at least for the first shot. Being a revolver guy, it works for me.
If possible, try both. But, in my opinion, for self defense/carry use, I think you'll be better served with the decocker version.
