DejaVu: My every day carry is a revolver as well. I carry a S&W 640 loaded 357 magnums and 1 extra speed loader.
I don't own any magnum guns but 4 revolvers only. Normally I carry my
CA 44 Spl Bulldog primary, and backup revolver is a S&W 38 Spl 642
My other two are a Taurus 851 38 Spl and a S&W 625-5 45 ACP, the
latter one I only carry with a fanny pack if I should carry it on occasion,
as it is a bit hard to conceal the way I dress.
I know others swear by their SA's and thats fine. I trust revolvers more myself. It seems like every time I go to the range to practice and the
range instructor shows me one of his SA's (including the one I qualified with)
they either have a malfunction with the magazine, or because it is an inexpensive one, or some other reason. I am not saying revolvers are better
because I don't have as many rounds without reloading or switching guns.
I do carry 3 Speedloaders of 5 rounds for the CA 44 Bulldog and one speeloader for the backup gun 38 Spl. I guess I just never got comfortable
shooting SA's although I use one to qualify with. I might eventually buy
a 9 MM SA. Just thinking about it. Oh, and I carry a small container of 10 loose 44 Spl rounds.
