L&M Precision Glock 19 RMR red dot sight intro and quick shoot

Mark Housel from L&M Precision Gunworks installed a Trijicon RM02 Ruggedized Miniature Reflex (RMR) sight on this Glock 19 (Gen 3 if it matters). The milling/finish work is flawless, the price is reasonable, and the pistol is a ton of fun.
