Overview
A solar-charging reflex sight built on the Delta Point Pro and DPP footprint, designed to mount directly to Sig P320 optics-ready slides without an adapter plate, with a 2 MOA dot, 32 MOA circle, or combined reticle option.
The solar charging system is the core feature here, using multi-directional light sensors to keep the internal battery topped off under most shooting conditions, backed by a rated 20,000-hour reserve for low-light use. Reviewers confirm the DPP footprint fits beyond just the P320 line, including Sig P320 AXG Legion slides and Springfield Echelon models cut for that footprint. One tradeoff worth knowing: it has no shake-awake feature, so it relies on light sensing rather than motion to wake from standby.
- Solar charging with light-sensor brightness
- 0.90 x 0.63 in viewing window
- IPX8 waterproofing, 5000G shock rating
- Multi-reticle: dot, circle, or combined
Who it's for
Handgun owners with a P320 or other DPP-footprint optics-ready slide who want a rugged, low-maintenance reflex sight for range or duty use fit this well. Shooters who specifically want shake-to-wake activation rather than light-based wake should check that feature elsewhere.
What buyers say
From Amazon customer reviews.
Reviewers across different pistols report the sight going on quickly and holding zero afterward, with several specifically praising fit on the Sig P320, P320 AXG Legion and Springfield Echelon slides. The solar charging draws repeat praise for extending battery life without owners needing to think about it, and brightness adjustment between indoor and outdoor ranges was called effective by more than one buyer. The one recurring criticism is the lack of a shake-awake feature, noted by a reviewer who otherwise rated the sight highly.
Strengths and trade-offs
Drawn from this product's published specifications.
- No shake-awake feature, relies on light sensing
- Only fits DPP-footprint optics-ready slides
Performance notes
The enclosed emitter design keeps debris and moisture off the internal lens elements, which matters most for a sight meant for range and duty use rather than sitting in a case. Brightness adjusts automatically through multi-directional solar sensors, with a manual override that locks in high brightness for 30 minutes when lighting changes quickly, such as moving from an outdoor to an indoor range. Reviewers across different P320 variants and a Springfield Echelon report the sight holding zero after mounting, with no adjustment needed once sighted in.
