That model is on an N frame, as also used for .44s and .45s for lo, these many years.
But a 581 is an L frame, not K.
I've had people tell me its L frame, K frame, N frame, and J frame.
Does this add any sort of collectors value if it's mismarked?
And to be clear, it's a L frame? RIGHT?!
Other than L being beefier than J and K frames, I don't know what that means.
People, outside of THR, told me it was a J frame.
Just wondering if S&W marked some or all of their revolvers underneath the grips on the frame indicating what frame type they were?
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.
Me neither. I don't own any newer Smiths.
I was just wondering if the K referred to what frame type it was, pardon my ignorance.
It wasn't the top strap that was the problem,
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.
