There seems to be a consensus that the 45acp still rules over the 40S&W, w/o creating a caliber war here, I was wondering if there were any advantages of a 40cal when shot out of a very small subcompact carry pistol, ie a Kahr PM40 (5.35in) over the larger/slower 45acp, in a similiar sized packages, the kahr PM45 (5.67in)
My one thought and please correct me if I am wrong, bullets regardless of caliber, lose their velocity as the barrel shortens, so I was wondering...due to the increased velocities of a 40, would the far better and prove more effective and stronger "on paper" as compared to the 45acp slower/heaver round from a similiar sized gun?
PS - I guess what I am really saying is that, can't the 45 do everyhting ther 40 can plus shoot heavier bullets. If you take a 40 and shoot 180grain @ whatever fps, wouldnt the 45 be able to shoot a 180grain @ the same fps?? I am trying to understand if there is an advantage to the 40cal that I dont understand.
