I got one of the "very good plus" condition S&W Model 64s from J&G Sales. It is a 4" K-frame (6 shot) .38 special with a round butt. It is the older style, with the firing pin mounted on the hammer and hand fitted forged steel parts. These guns are getting hard to find, aside from police tradeins, because the older generations of S&W revolvers tend to have better triggers, having been assembled with much more attention to detail. The gun came in better condition than I expected. The action feels brand new and the finish wasn't bad at all. I polished it up a bit, more for something to do than because the gun actually needed it. It does need a new set of grips, the soft rubber gets beat up easier than the stainless steel I guess.
The gun carries well. The K-frames are the thinnest 6 round revolver out there. I have no problem comfortably concealing the service sized revolver, with the stock "square butt conversion" grips. I use an inside the waistband holster from Blade Tech and it is very comfortable.
S&W K-frames point like a finger, having their barrel mounted slightly lower in the frame than other guns it aligns itself with the shooters firing hand and arm better. Recoil is felt less and instinctive shooting made much easier.
The revolver was extremely accurate. I had a chance to run 50 rounds through it and even firing fast using the double action only trigger I was able to print tight groups all the way out to 50 feet. Head shots at that range were easy and consistent. The gun handles very well.
I load it with the old "FBI Load" still manufactured by Remington. It is a .38 Special +P with a 158 grain pure lead (no jacket) hollow point. Something about it has worked well for decades, and it continues to do so. Most fixed sight revolvers are regulated to hit point of aim using heavier rounds, and this load does just that. It is also extremely easy to shoot due to very controllable recoil.
Anyone looking for a quality made revolver for defense or fun should seriously consider picking one of these up while they're available...
