I think I have 14 Pachy Decelotator sets for my 20 Contender frames. I too never liked the Presentation grip, but I have really liked using the Gripper's ever since they first became available. While they do help some on the handcannons, it's more that they just feel more comfortable and secure in my hand to me than even custom wood does (and I do love my custom wood sets). I don't like or use factory wood any more. Don't like the synthetic/composite sets either, but probably because I also don't like synthetic stocks on my rifles. They just feel "tinny" to me and are noisier in the field when hunting. I'm from the old school that believes a floated barrel is more consistantly precise, so do float all of my forends on Contenders whether in pistol or carbine/rifle configuration. The best place for a solid rest without disturbing barrel harmonics on these TC's is just in front of the trigger guard. Important when the target is small and the range long. But you can get near the same results with a floated forend rested on shooting sticks or with a bipod mounted to the floated forend.
So I guess IMO you get what you pay for and the Pachy's are worth the extra cost for my TC pistola's.
