You may think that one is enough...or you might find out otherwise.
If your first revolver ownership experience is a positive one, who knows where it will end? A lot of people feed their revolver addiction.
In the first 25 years of my life I only had one revolver, a Rossi that was such a POS that it nearly cured me of that itch permanently. For some reason (and twenty years later) I gave it another try and bought a 4" S&W M66.
Since then I've owned at least twenty S&W revolvers. At least three brutal Scandium .357 j-frames (none currently), a 6" M27 that I foolishly sold, and a very nice 4" M586 that just didn't feel right compared to the M66. And then a bunch more that weren't .357s...
If I were only able to have one, it might very well be that M66. It's an ex-LEA gun, not abused but nowhere near new. Just enough wear that I'm not the least bit self-conscious about carrying it or shooting it. The K-frame is the perfect size for me. Feels, fits, and balances perfectly.
I'd like a nice blued 4" M19 like HighPower's, but then I'd have to worry about keeping it pretty. My M66 has no such issues.
SavageCorn, that's some nice shooting with that hand cannon.
