Hello. At the same time that I bought a NIB Model 14, I also bought a Model 64-1 4" SB revolver in like new condition. It had been shot very little and served as a bedside gun for a while before going to the previous (original) owner's safe.
I shot perhaps a hundred rounds through it and was more than a little surprised at how perfectly regulated the fixed sights were for me with a couple of loads, one being Remington's 158-gr. LSWCHP +P.
Took the thing out a few days later and was blazing away with Winchester USA 130-gr. FMJ ammo when it began to lock up. It was a timing issue. The cylinder stop was not dropping far enough to let the cylinder turn.
At the bench, I disassembled and checked for any burrs, weak springs, etc and found nothing. Reassembled and the same problem existed so I took it to a gunsmith who happens to live a couple of miles away. A week or so and $25 later, it's working fine.
This one will probably be a frequent companion and loaded with a hard cast SWC to about 870 ft/sec or so. Though I much prefer blued handguns, I also appreciate the corrosion resistance offered by the stainless steel revolvers.
With each passing year it seems that older S&W's are getting harder and harder to find. To me, these things are like nice Hi Powers or 1911's: almost impossible to pass up.
It is "just a 38" but in a proven design and I like the "just 38 (Special)" cartridge quite a bit for many tasks including having fun.
I hope to do a "range report" type post with this one in the near future.
