I often wonder what the frame letters in the serial numbers on S&W revolvers stand for. I.E. N, L, K, J and such. I know they describe frame size but is the letter an abreviation for a word or were they selected at random. I found out that the old " S" designation stands for SAFETY. What about the others. Any help on this?

Thanks

The S added to serial numbers post WWII indicates the presence of the new style hammer block developed during WWII.

As to frame sizes and letters, I have never read that they stood for particular words. My assumption has always been that they were randomly assigned. I must confess, however, that I have never seen anything one way or the other in print.

Just a thought that they might have some meaning other than random. Makes sense now that you mention the hammer block. The addition of the "S" for safety. Thanks for the info.

If they were symbolic or stood for something, you'd think the Standard Catalog of Smith & Wesson would say so.
I have a copy (and read it) but have not seen anything in it to confirm or deny.
 
The letters indicate frame size and were used in manufacturing when building a particular gun. For example, NT-430 is the 44 Magnum, KT-357 is the Combat Magnum, and N-45 is the 1950 Army revolver. The K and N indicate frame size, the T stands for target and the number for bore diameter.

Often wondered why they chose..... J,K,N ....... and skipped "L" for 30-40 years..... and then jump to "X"

IIRC there was an "M" frame ....... which was smaller than a J frame?..... or was that the .32cal "I" frame ?

So over the years we've had I J K L M N and X...... but they don't all line up by size..... as M was the smallest!

The rest makes sense "S" for safety and "-T" for target.......

Why not L,M,S........LOL

Why do Stainless steel guns get E,F,H and G? (at the factory)....... when they came later?

Early guns were Model #s were 1,2,3....... why did they go to letters then back to Model numbers starting at 10 (in 1957)......... what happened to 4-9?

I've got the SCS&W but don't remember seeing any explanation!

Why not just L,M,S........LOL......we could also have XS, Med/L, XXS, XXXL

The person who would know is Roy Jinks. He knows everything as the S&W historian. Might give him a call.
 
I have a 686-3 SN BPHQ 497 anyone know what this means? BPHQ ?
It was factory tuned by one of their smiths I think as his name is stamped on the box.
 
Wondering why S&W does these things is an exercise in futility. Even the model numbers are all over the place, except for the blued N-frames in the 20's. Plus the reasons for engineering change (Dash numbers) can also drive you crazy. Some models it can be tiny and you get a new dash #. Then there can be big changes and no new dash #.
Only the folks at S&W 60-70 years ago can give any sort of answer.
 
Seems like there are different designations between blue steel and stainless also. I'm just going off memory here. Example a k frame blue would be a G frame stainless. Or something to that effect. G. H. I can't remember. I just realized it's already been explained above.

Always best to start a new thread for questions, but...

BPH is the letter prefix, from sometime in late 1993. It should have four digits after it so it may be 0497 or 9497. A photo would help.
 
Stainless revolvers used the letters E, F, G,and H. For example, the Model 66 is the FT-357 (a K-frame). I have no idea why the particular letters were used, but it is necessary to identify the specific model when issuing a build order to the factory. The Model 629 is the GT-430 (an N-frame) and the Model 686 is the HT-357 (an L-frame).
