What but style does your 357 have? A square butt is harder to conceal than a round butt. My Ruger Securtiy Six was a square butt. Ruger made round butt Speed Six guns, and the difference between them was only the material they left in the corner of the frame. I ordered Pachmyer Compact round butt grips for the Speed Six and modified the frame to fitt. I’d check the frame of your S&W to see if the same modification could be made to your gun.
