❓ Frequently Asked Questions (FAQ)
Q: What’s the difference between Shield RMS, RMS2, RMSw, and RMSc?
A: The RMS is the original lightweight optic. RMS2 improves durability with a reinforced glass lens. RMSw is fully waterproof—ideal for harsh duty use. RMSc is optimized for slim pistols like the Sig P365 and Glock 43X.
Q: Does the Shield RMS co-witness with iron sights?
A: Yes. Its low-profile design allows co-witnessing on many optics-ready pistols using standard or suppressor-height sights.
Q: What’s the battery life for Shield RMS sights?
A: Expect up to 2–4 years on a CR2032 battery, thanks to the always-on, auto-brightness LED system.
Q: Will these optics fit directly on my Glock 43X MOS or Sig P365?
A: Yes. The Shield RMSc and RMS sights use the RMSc footprint and fit directly onto those models with no adapter needed.
Q: Should I get a polymer or glass lens?
A: Polymer lenses are lighter and shatter-resistant. Glass lenses offer better clarity and scratch resistance—ideal for frequent users and professionals.
