First of all, I totally believe almost anything should be legal and available, including Hi-Cap mags and select fire. This is not a thread debating legality.
Are Hi-Cap pistol magazines in weaker calibers such as 9mm worth it for a regular civilian? I understand military and police needing a lot of rounds for covering fire, or for engaging multiple targets. But for an average Joe, it seems like you don't really need 15 shots. 10, or even 8 would probably do with your standard mugger or home invader. So why not use a more powerful cartridge like .45ACP with an 8+1 round weapon? 9 rounds total seems like plenty for most anything one would come up against in normal life, plus the more powerful cartridge usually has better performance. It seems that those extra 5 or 6 rounds are a worthy trade for more power since most people won't really need to empty a 15rd mag in a mugging or burglary situation. I know the recoil on 9mm is a lot less than .45, but that is kinda besides the point. My premise is that you will almost never fire more than 3 maybe 4 shots at a mugger or burglar. Who is really gonna empty 15 rds at some petty thug? Wouldn't 1 or 2 more powerful shots be a better trade?
Also, I know some people with small hands or arms might not be able to really handle a larger cartridge. I mean for people who can handle either, but choose something like 9mm for the Hi-Cap.
