Why buy even a used one? That helps validate to the lipstick and miniskirt fans of Smith (those who'll bend over and take it and smile) that they are good guns with good resale value.
I won't buy one for $20. Not as a gift. To me, a Smith is worthless. I'd rather buy a junk Bryco, because they at least ARE fighting the war. (Didn't say I'd USE a Bryco...).
First of all, &'s autos are crap. End of story.
Second, they make a damn good $250 revolver. The problem is, they want $500 for it. You get the same guarantee from Rossi and Taurus, and better politics. The Taurus 606 ported .357 snub (already discontinued for the 607 7 shooter) is as fine a concealed revolver as one will ever find...got it for $219. Why would anyone waste money on a Snitch & Wussy?
Ruger GP100 is a fine gun. Colt (also ugh!, but...) Python is a fine gun.
Nor will I buy anything in .40 cal, just on principle. When they are dead, buried, the grave desecrated and bulldozed into a parking lot and forgotten, then I'll consider buying a few as collector's pieces. "Smith & Wesson? Oh, yeah! Let me tell you what happened to THEM!"
To quote L. Neil Smith: "Smith & Wesson must die!"
And AFAIK, the new owners have no legal obligation to continue an agreement signed by the last owners. So screw them, too.
