I'm looking around and I've found only one maker so far.
It's called Marschalgrips.com
I like what I see....apparently you can get finger grooves and a thumbrest but really I see no need for that on what would be a carry pistol (hell I might need to use either hand in some cases)
At first I was sold on this grip as this was the only picture I could find with the grips on there....but then I realized...it stands out...not a good thing for a future carry pistol
What do you think? I'd like to know if anyone else does it...so I can compare and contrast...and hell I'd really like to put this emblem on there somewhere.
