You know you can shoulder them right?Muzzle blast isn’t too bad if you install a Flaming Pig or similar in place of the flash hider, it directs the blast down range. I have a Flaming Pig on my AR pistol and it helps a lot.
As for the CZ, you could have the pistol barrel installed instead of the carbine barrel but you obviously would have to remove the butt stock. My Scorpion pistol has a folding brace, I like it without even shouldering.
