You may need additional parts if you’re using this to attach pistol optics - Fix It Sticks All-In-One Torque Driver Kits

Definitely need to get an hex entender if you’re using this to attach RDS to pistols. The torque driver is wide and won’t clear on top of the RDS housing. Also doesn’t have a T8 size bit which is used on Sig pistols. Otherwise a good product.
