The Meprolight MPO Pro-S (model/part number 901141282) is a compact closed-emitter pistol optic with a green reticle option. It features an RMSc/JPoint® footprint, making it suitable for direct mounting on many subcompact and compact handguns (e.g., certain Sig, Springfield Hellcat, or similar models with RMSc cuts).
Key Specifications
- Emitter Type: Fully enclosed (sealed against dust, debris, moisture; IP67 waterproof and fog-proof)
- Reticle: Selectable 3-segment green — 3 MOA dot only, 33 MOA outer ring/ghost ring only, or 3/33 MOA bullseye combination
- Brightness: Auto-adjusting sensor + manual override (10 daylight settings + 2 night vision compatible)
- Battery: 1x CR1632 (20,000+ hours life on medium setting; shake-awake and auto-sleep/power-saving modes)
- Adjustments: 1 MOA per click, ±30 MOA total travel (windage/elevation)
- Lens/Window: ~0.78" wide x 0.60" high
- Weight: 1.4 oz (very lightweight for EDC)
- Construction: Rugged aluminum housing, built for military/law enforcement durability (direct impact resistant)
- Other Features: Side-mounted controls, low-profile design to reduce snags
- MSRP: Around $279–$320 (street price varies; green version may be similar or slightly higher as a newer option)
This is the closed-emitter sibling to Meprolight's open-emitter MPO-S. The enclosed design offers better protection in harsh conditions while remaining compact for concealed carry or duty use. Green reticles were introduced/expanded for the MPO Pro series around early 2026 (e.g., at SHOT Show), as some shooters prefer green for certain lighting or eye conditions over traditional red.
Typical Use Cases
- Everyday carry (EDC) on micro-compact pistols
- Duty or defensive handgun setups
- Backup optic or co-witness with iron sights (depending on mount height)
