Are S&W's marked under the grip with their frame type?

Just wondering if S&W marked some or all of their revolvers underneath the grips on the frame indicating what frame type they were?

Any help would be greatly appreciated!
 
Under the grips? No. Some, not all, have a serial number prefix denoting the frame size; but not enough to count on. If you look at enough guns, the differences become apparent.
 
Bill, you have a 'K' frame 581 Smith and Wesson fixed sight, blued 357 magnum with full barrel underlug in 357 magnum caliber. The factory mismarked the "581" in that they stamped a hyphen between the 8 and the 1. They do things like that sometimes.

I happen to own a model 25-2 which is a 1955 target. Only, the gun I bought was part of a lot where the guy stamping barrels that week stamped the barrels as "1950 target." I had a heck of a time figuring out what I had, but it turns out I had a mismarked gun.
 
But a 581 is an L frame, not K.

So it is. And I knew that. I even posted the distinction on this thread.

So, Bill, what that means is that, on the other thread, when I discussed the forcing cone problems re the 'K' frame (since you were contemplating buying a model 19, which is a 'K' frame), that doesn't apply to your gun. The 'L' frame is beefier and isn't subject to those problems.
 
Don't know how much collector you are; but a copy of The Standard Catalog of Smith & Wesson by Nahas and Suprica is a must if you are into S&W's.
 
I've had people tell me its L frame, K frame, N frame, and J frame. lol

Does this add any sort of collectors value if it's mismarked?

And to be clear, it's a L frame? RIGHT?! lol
 
It's on the L frame, dadblast it.

The bad news is that a minor mismark that would lead someone with only "58-1" to go by to think you had a .41 magnum is not going to add anything to the value. It's not like a stamp or coin that is worth more because it is wrong.

The good news is that the fixed sight L frames - 581 and 681 - are getting a cult following and are gaining in resale value just because they are not real common and have that businesslike look.
 
I've had people tell me its L frame, K frame, N frame, and J frame.

Well, in all fairness to the 'N' frame people, you said you had a model 58-1. The model 58 is an 'N' frame. 41 magnum. That was your fault.

I didn't see anybody post that you had a 'J' frame.

I said you had a 'K' frame. I knew better since I posted as much last year on this thread.

But I had forgotten it.

Probably not. It's not one of those things collectors look for.

Yes, but do you know what that means?
 
The gun says 58-1. It S&W's fault, don't blame me!

People, outside of THR, told me it was a J frame.

No added collectors value, eh? All the more reason to carry and actually shoot it :D

Other than L being beefier than J and K frames, I don't know what that means. This is my first S&W.

Me neither. I don't own any newer Smiths. But it's not the whole frame that's beefier. The grip frame, for example, will use grips for 'K' frame revolvers. So, the grip frame is the same.

The only thing I know that's beefier is the top strap. The 'K' frames not only had problems with the forcing cone, but also with flame cutting the top strap. The 'K' frame top strap was, I guess, too thin for some magnum loads.

Ok, now that's funny.
 
The cylinder of the L-frame is larger around then in a K-frame.
1.43" vis 1.56"

This larger frame window allows the barrel to be full diameter over the gas ring.

The K-frame had a flat milled on the bottom of the barrels forcing cone to clear the gas ring, which sometimes cracked.

S&W did mark the grip frame sometimes with the finish that the gun left the factory with. If your 581 is Nickel finished (or originally left the factory that way regardless of what it is now), and you pulled off the grips, the grip frame would probably have a large capital "N" stamped on there. This refers to the factory finish, not the frame size. Stainless guns had an "S" and blue guns usually had no stamp at all.

The only thing I know that's beefier is the top strap. The 'K' frames not only had problems with the forcing cone, but also with flame cutting the top strap. The 'K' frame top strap was, I guess, too thin for some magnum loads.

It wasn't the top strap that was the problem, it was the forcing cone diameter and the amount of frame around the barrel as rcmodel said. The extra 1/8" diameter cylinder also necessitated making the frame window 1/8" taller, of course, and this resulted in extra steel around the barrel threads and especially directly below them, where it was thin.

Me neither. I don't own any newer Smiths.

The L frame debuted in 1980. So it's going on 30 years old - plenty of time to get acquinted - it's no "newcomer"!

thank you sirs.

Regarding the OP, the grip frame has a big "K" stamped on it along with the same numbers that the cylinder crane has. There's also, what appears to be, a little crown stamped on it.

I was just wondering if the K referred to what frame type it was, pardon my ignorance.

Thank you again

Those are meaningless numbers - they only relate to each other. They are called "assembly numbers" and are to mate a crane/cylinder assembly to a frame after they have been hand fit. That way if they are separated for finishing or any other reason, they can be mated together again w/o worry of parts mis-match.

I see how the "K" confused you since it was also a frame size. But no, there was never a pattern of marking frame size on the gun, only s/n, assembly numbers, finish type, and occasionally other odd assembly stamps or refinish-stamps.

I saw your pics in the other thread and what you have is a Blued-steel 4" S&W model 581 with some aftermarket pachmayr grips, it appears, like the other posters stated.
 
It wasn't the top strap that was the problem,

That's not true.

The 125 grain bullets driven to maximum velocities used large charges of relatively slow-burning powders. Handloaders know the powder types as WW296 and H-110, among others. The combination of slow ball-type powders and the short bearing surface of the 125 bullets allows prolonged gas cutting of the forcing cone and top strap area, accelerating erosion and wear.

There were indeed cases of the top strap suffering extreme erosion from the light bullet/slow powder combination in some magnum loads, and because the k frame was thinner, some k frame magnums showed dangerous damage.
