The S98 is an eccentric, titanium, and full-welded suppressor designed for 9mm handguns. Because it's eccentric, the bore sits below the shooter's line of sight for a clean look and unimpeded sights. The S98 is a premium suppressor with incredible sound performance, especially considering its lightweight construction. The S98 is rated for 9mm handguns only. It ships with a 1/2 x 28 QD Mount, (AC22 not compatible).
