As a cop, I used to carry off-duty a Chief's Special, or a Model 15, or a Model 27, or a Model 66, or a Sterling 302 .22, or a Mauser HSc.
I never got into a gun battle, or had to draw my off-duty gun. I hear some stories from time to time about off-duty cops who have gotten into a shoot 'em up, but I have hardly ever heard of a CCW person who got into a shooting situation. I've seen the accounts of home and business owners who got into shootout, (AMERICAN RIFLEMAN - ARMED CITIZEN page, FACEBOOK) but other than that, nothing.
So I get to wondering, does it really matter how many shots you have, or if your gun is 100% reliable. Shoot, even in my pistol and rifle leagues, I get duds in my .22 ammo and have to rack the slide or action fast to get more shots off. Even my centerfires sometimes smokestack shells. (My revolvers don't)
Anyway, I just got to wondering about this after seeing some of the slightly negative comments going back and forth.
If you have taken care of your gun, not let oil get into the shells, it should work, and you probably won't need to carry much ammo, either.
