?????? There is more than one way to skin a cat. You skin yours however you want.
OP: The CZ is great, it is my preferred shotgun, but out of the box the springs would work just fine on a Mack truck. But for me the hammers are the right distance apart. I can cock both springs with one thumb and the hammers are far enough apart that my perifial vision is good. The TTN and the pieta both have hammers that are closer together and limit my perifial vision to the point I feel like I’m looking through a tunnel. Out of the box the springs in the pieta are much more user friendly. The wrist feels very small and thin on the pieta as well. I hope this was useful.
