They are very comfortable for me. I like the smooth ones without finger grooves, as shown in the picture. The bottom part helps control recoil and gives the bottom finger of your support hand a place to grip. Good for matches with fast draw required because it funnels your hand to the same grip every time very quickly. Good for shooting prone, gets the sights up higher so they're easier to see and line up with the target. Shooting off a bench works with regular or big butt grips.
