Larry Potterfields conclusions are crap if you are going to base your own carry gun on them. There are to many variables that will depend on the individual shooter, such as concealability, number of shots in a given length of time (5 Sec. if IRC).
They are only valid if you use them in your own comparisons.

Well yea what you see in the video are his scores. That's why I'd wanted to find the charts especially for the last part the ammo. I want to score how I shoot with my own guns. I have a bunch of different guns and several of them have specific designs to make them different. But I want to compare the apples to apples like my P229 .40 to M&P9, M&P9c to 340PD, 1911a1 to M&P45, guns of similar size and power. I have my favorites but I want scale or grade them in my hands. I appricate the help. I really like the handloads site!

I like the comparison. I also want something to help me convince my Mother to change carry guns. She's reluctant to switch to an autoloader.

I think a gradable scale will help here see the light!
