For those looking for a little more firepower for their 9mm 911 pistol, this extended seven-round magazine fits the bill. Featuring a slick stainless steel body, round-count witness holes and a tough stainless steel follower, the extended magazine has a polymer sleeve/bumper that follows the contour of the pistol's frame and extends your grip.
