Model 19 pc grip question, are all K frame grips interchangeable?

[Fluffy Medic]

I have a model 19 performance center carry comp round butt with unmarked rubber grips that need replacing. I have located some smith and wesson marked replacement factory rubber grips at a popular online parts dealer. The first set says they fit models 66, 69, and 686. The second set says they fit models 64, 67, 617, 686, 386. So my question is are all K frame grips the same size with the only difference being square or round butt? Thanks in advance!

K Frame Grips

Yes, all round butt k frame grips fit any round butt k frame.
Square\Round is the only distinction

There is round to square conversion grips

There are lots of options for K frame RB as they are all the same size. S&W, Hogue make good shooting rubber grips and there are a lot of aftermarket wood and laminate grip panels available. Some people like these as they come in different color/ patterns. I have 1 pair I think they are G20s made by Hogue. Here's a link to Hogue...they have quite a selection of grip types and styles.

K/L-Frame Round Butt - K/L-Frame Revolvers - Grips for Smith & Wesson - Handgun Grips - Hogue Products

My favorites though are the S&W RB Combats.
