I have lots of CZs and one Glock.

I have big hands but prefer the feel of even my tiny 2075 with the standard magazine over the feel of the Glock.

I took a shooting course from someone who offered people who didn't own guns to use his Glock 19. Let's just say that the Glock reputation for reliability is a little inflated. My CZs are at least as dependable.

The added benefit with a CZ is that if you have a primer that isn't quite struck right by the first shot you can pull the double action trigger for another go at it. Can't do that with a Glock or an XD. If your first strike doesn't set the round off you have to rack the slide.

Murphy will dictate that if you are ever going to have a bad primer you will probably have it when you need that round to go off the most. If you have a double action semi-auto then you will have another chance at striking that primer. You won't with a Glock or XD.
