S&W Frame type question?

[ExtremistPullup]

Hi all
I inherited a .357 s&w and need help identifying the grip type for a replacement. I'm not too familiar with these. Six cylinder, I believe it's a m 66-2
Thanks for the help.

The model 66, my personal favorite, is the good ol' K frame.

Yep, what he said.
Also, K and L frame will interchange. Not to confuse you, but IIRC, Z frame (Governor) and X frame (500, 460, 350) also fit K's. Currently round butt only.

That's a square butt K frame.
