This product replaces the magazine base plate and the internal locking sub-floorplate. They alter the capacity of the M27 and M33 magazines increasing them to ten rounds (legal limit). They also provide extra grip length for better control and comfort. These units blend with the contours and texture of the handgun giving a factory appearance. They form the next logical finger positioning feature to provide control and comfort without sacrificing concealability
Adds +2 rounds to 9mm magazines.
