J's, K's and 1911's.
My very first gun was a blue, 4" .38 (hand-me-down). The first carry gun I bought when I got my permit was a 640-1 in .357. I no longer have either.
I have bought, sold and traded all manner of handguns and been through high cap 9mm's; mini .40's; derringers, microscopic .22's and pocket autos in .25, .32 and .380. I've spent time with glocks, PPK's, Beretta's large and small and a Taurus or two...even a Raven .25!
I feel I have come "full-circle" in my tastes. J- and K-frame S+W's in .22 or .38/.357 and .45 1911's are all that really interest me anymore. Oh, sure I still get the itch now and again for some type of 9mm or hand-cannon revolver in 40-something, but I resist buying and stick to the above. If I want variety I'll go shooting with a friend and shoot something they have that I don't. Besides, I could stick to my J's, K's and 1911's and because of all the configurations and finish variations, keep buying for a very long time and never get all of 'em!
