Marvin's Review of Guntec USA AR 9mm Cal CAR Buffer and Spring Set
This thing is money. It slows down the bolt travel perfectly for 9mm rounds. For the price, this is the best option out there. You need this in order to prevent smaller 9mm rounds from getting bent or slammed hard by a fast traveling bolt. It also helps slow down the hammer reset time.
