S & w 617
The 617 is hard to find. I have both the 4" and 6" that I use at our .22 club for plate matches. Got the 5-Star speed loaders and great to shoot. From what I understand that Smith & Wesson only makes these a few times a year. That is why they are hard to find, plus that they are in demand.
God bless America and our troops. USMC
