I ordered, received and installed the grip pads and a new sleeve from AGlaser the other day. Note that he delivered two sets of pads, and some folks hereon have installed them both at once. I did not. I installed one set and pulled the sleeve over them. I got a chance to put them through their paces in an extended range session yesterday. By extended, I ran 275 rounds through my P3AT yesterday in an hour and 45 minutes. The pads definitely reduced the felt recoil. My very subjective and unscientific estimation would be a 20 to 25 percent reduction. This is my second sleeve from AGlaser and this one is a little better quality than my first unit. My only beef is that it began slipping lower (toward the end of the grip) after every 50 rounds or so. Obviously not a "real" problem that would affect the use of the weapon in a "real", two-magazines-or-less-type situation. I will probably consider some sort of an anti-slip solution (I am open to suggestions). Overall, it is my opinion, that this kit from AGlaser is a "must have" for any P3AT owner. It is inexpensive, simple and does what it advertises. Two big thumbs up from me. Edited to slightly amend the verbiage in the second to last paragraph so as to further emphasize that this is my opinion.
