Good news - Hand filling, geat for comfortable, accurate shooting.

Bad news - Opposite of concealment. They are essentially as large as K frame grips.

Depending on your usage and needs, you will either love them or hate them, but probably not middle ground.

If the implied question is ' what grips provided pretty good control, while still being conceable? " , the best answer is Boot Grips from any grip maker still cataloging for J Square. Second best is Magna's with grip adapter.
