I have been seriously thinking of trading my G21SF for another G22. Maybe I am nuts, maybe it is sacreligious, but I am tired of searching for 45 ACP ammo, bullets and the ilk. I can find 40 S&W all day long, but 45 ACP, I might as well try finding hen's teeth. Someone, anyone, please, feed me your opinions. Am I crazy? Well, that is debatable. But am I just kicking stones or is this a serious disease? Even comparing the 40 S&W to the 45ACP there's not much difference between the two, except bullet size, and the .40's are so much more accessible than 45 right now. This has been a dilemma for me going on for a few months now. Maybe, just maybe, there is some light at the end of the tunnel... Brad L.
