I shoot Fiocchi 158’s suppressed 100% of the time. All the 147s I’ve tried function fine but aren’t subsonic 100% of the time.
Have probably spent an additional $450 on mods to make it a better gun than the stock pistol config. Some of that is subjective and preference more than function.

My SB brace locks up like a bank vault.

IME, the CZ owns its price point and up until one gets up to the MP5 clones, which I also have experience with and generally prefer.
