I agree with you in that I do like mine as well. It makes the recoil much softer, not that it was bad to begin with. Have you run your gun with the "newer" Enidine very hard with good results?

that's the replacement i mentioned in my post. as far as 'hard' - not as far as going through a 3-day class, but just during one-day range drill sessions of about 500-600 rounds, doing what you'd normally do in a class. i've got about 2K round on it so far, i'd estimate.
