I have Model 60-7 Ladysmith with a grip that works well, but no manufacturer on it. Just says "S&W J-Frame Round Butt" on the inside.
The Model 30-1 wears a set of Hogue Monogrips and I like them a lot.
Honestly both fit my hand about the same. Can't say I have a favorite between the two.
I believe at one time Pachmayr offered their grips with or without the medallion. Unfortunately, its medallion only these days. Although I would prefer them without.
