Is there any interest in see a comparison of reload performance between a Kahr pistol and other brands/types?

There, that's out of the way.
First example: 45ACP with Power Pistol powder and Berry's bullets. At the range I shot these over the chronograph using my Kahr CW45 and a 1911 with a new Roto4m barrel.
Load: 8.8gr. Power Pistol, Berry's 185gr Plated Flat Point, CCI primer, WCC71 brass
Kahr CW45 (3.64" barrel): 1031 fps, 33 fps extreme spread
1911 (Roto4M 5" barrel): 1152 fps, 40 fps extreme spread
Difference: 121 fps, 10.5%, with 72% of the barrel length of the 1911.
Second example: 9mm with SR7625 and Rocky Mountain Reloading 115gr. Plated Hollow Point bullets. This has been my most accurate 9mm load to date. I shot these from a CM9 and a SCCY CPX2. Both have about the same length barrels.
Load: 4.7 SR7625, RMR 115 gr Plated Hollow Point, WW primer, FC brass
Kahr CM9 (3.0" barrel): 982 fps, 73 fps extreme spread
SCCY CPX2 (3.1" barrel): 979 fps, 60 fps extreme spread
Difference: 3 fps, 0.3%
The comparison between firearms is what I think is interesting. Seeing that with Power Pistol I lose more than 10% compared to a 1911 is amazing to me. Can't wait to see how faster powders compare between these two guns.
Let me know if you're interested. I can add more data as I collect it.
