Shield Sights showed up to SHOT Show 2019 with their new RMS-W to display. This waterproof pistol red dot now features a gasket seal underneath it which will keep it waterproof to 20-meters deep for up to 30 minutes. They have beefed up some of the framework around the top of the sight so it has a little more weight and strength. This should give the optic a better feel on top of the pistol while making it tougher at the same time.
Along the side of the sight you’ll find threaded drain holes which can serve to mount accessories, if you’re into that sort of thing. The lenses of all Shield Sights have now been coated in a quartz coating on top which will make them more durable.
