Used Gen 3 Glock 20 SF 10mm with Trijicon RMR06 red dot sight and 2 used, 2 new-15 round mags. The slide has been custom milled to accept the sight. This allows the sight to sit lower in the slide, allowing for normal sight aquisition. It has suppressor height sights installed to act as back-up sights. I have also installed Talon grip tape.
