The JMT Mk ll Mod Vl sight pusher is a very heavy duty tool capable of moving very tight sights. It will work with most pistols with flat slides and dovetail sights. Though it was originally designed with the 1911 and S&W autos in mind, it will work on a wide range of other guns. Glock, HK's, Rugers, and Taurus to name a few. Obviously, those with slide mounted safeties must have the levers removed. This model is not recommended for Springfield XD's. There is a different tool now in production that will fit the XD. The prototype has been successfully tested, and the Mklll "Xtreme Duty" is now available.
