I'm a newbie at CCW, only for a few months so far and I have to say, I like the idea of a manual safety. With a striker fired pistol, you are carrying a live round in the pipe and the striker is cocked. I have been working on thumb sweeping the safety upon presentation, so far in practice, no problems.
I am contemplating getting a Glock 36 though and I know with Glocks, no manual safety and you are walking around with one in the pipe and the striker cocked. Guess I just have to get used to it. I have good trigger discipline but in the heat of saving my own life, I just need to make sure that I keep my good trigger discipline.
