This has likely been discussed here, but I'm not finding what I want with the search engine. Short version is this - I'm seriously considering a carbine as a shtf purchase. My wife already shoots a C9 and my other handguns are either 9mm or 38/357. I also totally get that the .45 makes a bigger hole (I come from a pre-Beretta military era). Is there a practical reason for me to buy a .45 carbine over the 9mm? Looks like both are pretty accurate to 100 yards. What say you?
