On some of the PC guns and special variations of others, the serial number prefix would seem to be significant in that it stands for something. Here are the ones that I have noticed:

CSH - from the Lew Horton Case Hardened Heritage Series (Model 24-5)
TWT - from the Texas Wagon Train commemorative (Model 544)
SUP - from the Banger's .38 Super N-frame (Model 627-4)
HEG - from the Sports South Heritage Series (Model 25-10)

The last one (HEG) is a bit of a puzzler. I'm assuming the "HE" is Hand Ejector, but I'm not sure what the "G" stands for, unless it's simply Gun. Any help here would be appreciated.

How about other special prefixes - please add them to this thread.

Adios,

Pizza Bob

There are PC 627-3 V Comps with a "NWR" prefix. I'm guessing that it stands for "New World Record" in honor of Jerry Miculek's 8 shot speed record. But this site's resident expert on the Model 627 doesn't believe so.

edit to add..

"CFR" for Camfour (distributor). I've seen this prefix on PC semi-autos more so than revolvers.
"KCP" Model 19 K-Comp
"LMH" PC 686-4 "Light Magnum Hunter".

I'll add a couple that are more then conjecture.

RSR for RSR Group, used on their late 90s era 629-4s and 657-3s. These were in the slab sided Light Hunter Configurations built by the Performance Center.

And a rare one, ERV for Ernie Robert Vedersen, of Snake Eyes golf fame who joined S&W to design S&W Golf clubs in the early 2000s under the name Vedersen Design Group (VDG). The head of these clubs were forged by S&W.
