I carry a PCR decocked. That essentially puts it to the half cock position.
I dont see how thats any different than carrying a safety equipped CZ with the hammer down or half cocked and the safety off.
Frankly, I love CZ's but I only carry IWB and my most comfortable holsters will not keep the safety engaged. Therefore, I have moved to decocker models and have learned to love DA/SA carry. It allows me to have my 3.5 lb - 4.0 lb SA with a deliberate 7.5 lb pull for DA. To me, thats perfect. If I ever go back to carrying my 75 Compact, Ill carry hammer down, DA/SA.
Ive tried everything and I cant get a stiff safety on my CZ's. So for me, cocked and locked is for 1911's and BHP's.
In other words, half cocked carry is a popular and entirely reasonable way to carry your CZ.
