I think G.A. Heath meant there will be slightly less recoil with the Pro than the Ultra. I own both and like them equally.G.A. Heath wrote:there will be slightly more recoil with the pro than the ultra carry due to the 1" shorter barrel and slide and the half inch shorter grip. The reduced mass will affect it slightly, but to me not that much (fair warning: I am a recoil junkie, which means I have shot a 454 casull with blisters on my hand and didn't mind it much).
The recoil is less of an issue for me than the shorter grip length of the Ultra. However, both carry nicely, are very accurate,
and function flawlessly. I find I carry the Ultra slightly more often than the Pro..... I shoot more rounds at the range with
the Pro..... go figure.
