Thanks Guys. I'll experiment. THe two thumbs forward as per Brian Enos's hold sure works with the CZ75 and it brings the barrel back down fast for the next shot. There just seems to be a lot more room on the CZ and the safety is more of a glunk, glunk, other than gradually coming on from a thumb touching it on the 1911. I'll try the thumb on top but I'm sure nervous about slide bite with a timed shoot from the holster. I'll do a whole lot of practice with snap caps I think
