Going from a steel 5" to an alloy 5", I found the alloy 5" great to shoot. The alloy 5" did not feel all that different than shooting the steel 5". The alloy was much easier on my back for carry. Then going from the alloy 5" to the alloy Commander, I found a remarkable difference in shooting. I attribute this to how the Commander has the slide cycle shortened in it's rearward travel as much as the 3/4" shorter barrel. I know the barrel must tip up more in a Commander than it does in a 5" but I don't know how much. My Commander just seems to cycle much more quickly and violently than my 5" 1911's. I'm sure looking forward to getting away from that 23,000 psi +P stuff. But even shooting my 452374 over 6.0 gr of Unique at 830 fps the Commander is not pleasant to shoot.
