PWS unveiled their new Glock EDS (Enhanced Duty Slide). You provide your own barrel and recoil spring but it is a simple drop in upgrade. The rep said they did not want to make any modifications to the frame or trigger of the Glock yet were able to bring the factory trigger pull down from 5.5 lbs to 4 lbs. There are forward slide serrations on the EDS. There will be two models. One with factory plastic Glock sights for $449 or with Trijicon night sights for $549. No optic option yet.
