Hey guys, I'd like you to help me make a decision. Especially those of you who are more familiar with ballistics.
I currently have a Kahr PM40 with a 3.08 inch barrel with 1:16 right hand twist. I have been very happy with the pistol, but am seriously considering selling it, so that I can get a Kahr PM45, with a 3.14 inch barrel with 1:16.38 right hand twist.
One of my big reasons for doing so, is I've heard so many on this forum speak highly of the .45ACP caliber, with .40 S&W not being as popular here.
My primary question is, considering the short length and twist rates of these barrels, which caliber do you think would be more effective in this size? I read somewhere that because .45ACP is slow to begin with, it might not be very effective in a barrel this short.
Your thoughts?
Here is some more information about these pistols:
