Why Not a .357 K Frame?

[Stephanie B]

I understand the old rationale that the K-frame wouldn't stand up to the pounding of light-bullet full-charge .357s, that there would be flame-cutting of the top strap and cracking of the forcing cone.

But still. Smith & Wesson can and does make J-frame .357s. So apparently it isn't only a matter of the size of the frame.

Why can't they now make a .357 K-frame?

You would think they could reinforce the frame somehow and also make a 327 out of it also. If the J frame can take the abuse a restyled K could also. Larry

Maybe I don't understand your request. Smith & Wesson makes .357 K Frames. My first S&W was a Model 19 6".

They used to make 357 K frames, models 19, 66 & 13. They didn't hold up, hence the L frame was introduced.

They don't make them anymore.

The K frame model 19/66 design left the rear of the barrel too thin for extended .357 firing, especially HV light bullet loads. It was designed for extended .38 and occasional .357 firing.
So S&W made a modified K frame version with more meat in the barrel/frame; it is called the L frame. You can shoot HV .357 all day in one.
Remember, when you sell a gun with a lifetime warranty, you find out if owners will cost you money by abusing the guns, and change the design as needed.
