Running the G17 Gen 5 and G19 Gen 5 MOS pistols through their paces, I found there are a variety of small, compact red dot reflex sights available. What features do I like in a reflex sight? I like a small foot print, the ability to change the battery without removing the sight (and having to re-check zero), long battery life, and automatic brightness adjustment for the red. Also add, tall iron sights in the event the red dot fails.
The Shield Sights RMS-W checks a lot of those boxes. This is the water-resistant and ruggedized version of the existing Shield RMS sight.
The RMS-W is designed to resist damage from water or other harsh environmental conditions. It has a gasket seal to create a watertight fit between the slide and the battery compartment without the need of a special mounting plate. When properly mounted, the sight it will remain watertight at depths of up to 20 meters for 30 minutes.
The RMS-W also features a new frame that adds thickness to the aluminum lens housing as well as a newly designed side profile. These modifications have increased flex strength of the standard RMS sight by over 80% while maintaining the original viewing window and mounting footprint.
Other Features Include:
- Hard coated polymer lens to resist scratching
- Very fast automatic brightness adjustment
- Very low profile to Co-Witness standard iron sights
- 2-3 year average battery life with standard CR2032 battery
- Weight: .62 ounces with battery
