M4C Newsletter & Larry Vickers: .45 vs 9mm; The debate is over
An exception to that in my opinion would be if you are stuck for whatever reason to carrying ball Ammo only. At that point all the calibers are just gonna poke a hole in the bad guy and a bigger hole is better than a smaller one so .45 ACP rules. That leaves .40 S&W out in the cold in my opinion and that trend is seen everywhere now as the .40 has quickly become the black sheep of the whole Ammo debate. The guns are harder to shoot, hold less bullets and are no more effective on the street than 9mm. In fact some have proven to be problematic for many years (Glock 22) when there 9mm counterparts are gold standards for dependability and reliability (Glock 17).
So that's the way I see it; 9mm is in, .40 is out, and .45 if needed. Be safe, keep shooting, LAV out.
