The Hogues are pretty thin profile, very ergodynamic, fit the shape of the hand. the Pachmayr Grippers and Signatures are bigger for bigger hands, wider, more hand filling. I, personally, can't get my hand all the way around the Signatures on my TC Contender, but I like 'em on that gun because they absorb a bit of the recoil. The older standard TC grips are aweful. The grippers are finger grooved and if it says "pro", means they don't cover the back of the grip frame, give you a little shorter reach to the trigger.
