Different guns are, different. See that all the time.
The 115's that work so well in my CZs are pretty bad in my M&P 2.0 5". The 124 FMJ Winchester ammo that helps the M&P do better than anything else I've shot in it don't do anything for the CZ's.
The 135 grain .40's that do great in all my CZ .40's do nothing to impress me in the FNS or M&P .40s. The 180's that barely make the FNS worth carrying don't do for beans in the CZ's.
I hate it, but it's real.
