💬 Frequently Asked Questions

What’s the difference between the Shield RMS and RMSc?

The RMS is the original full-body design, while the RMSc is a slightly shorter and more compact version. Both share the same mounting footprint, so they’re cross-compatible with slides cut for RMSc.

---

Will the Shield RMS co-witness with my iron sights?

In most cases, yes — the RMS sits low enough to co-witness with standard-height sights on slimline pistols like the Glock 43X MOS and SIG P365X.

---

How long does the battery last?

The RMS uses a single CR2032 battery and can last up to 2–3 years under normal use thanks to its auto-brightness feature.

---

Is the Shield RMS waterproof?

It is weather-resistant and sealed against moisture and debris. For full waterproofing, Shield offers a variant known as the RMSw.

---

Does the Shield RMS come with mounting screws?

Yes. The optic ships with screws and tools needed for direct mounting to slides cut for the RMS/RMSc footprint.
