I let a solid 4" M65 slip through my fingers about a year ago, been kicking myself ever since.
This weekend I wasn't able to shoot, but did quite a bit of dry firing and also just examining how my hand fits around different grips. I found that grips with a more circular shape right behind the trigger guard (most S&W grips that don't cover the backstrap) don't feel as stable to me as grips with an elongated oval in the same area (Lett grips for GP100). Makes sense that with rounder grips it would be more difficult to control rotational forces.
