One of my favorite S&W pistols and possibly my favorite. S&W dropped the ball on these when they discontinued them, IMO.
Let me see:
Single stack
9mm
stainless steel
Ambi safety
TDA
LNIB
What more could a Smith and Wesson fan ask for.
I don't think 500 shipped is out of line for a LNIB in demand ss pistol (if you break it down 450 for the gun and 50 for shipping or 475 for the gun and 25 shipping its a fair deal either way). You can always get a 3913 series etc, it may be a long long time before you get a chance to buy one of these.
It's a very fair deal. Nobody is making out like a bandit and nobody is getting ripped off.
Hope you get it and good luck with it
