The Genuine All-Rounder for Duty and Competition.
The Vortex Defender-ST™ steps up from CCW-focused concealment into a genuine everyday carry, duty, and competition optic — a larger window, the widely-supported DeltaPoint Pro footprint, and roughly triple the standard battery life of the Defender-CCW.

Product Overview
The Defender-ST represents a genuine step up from CCW-focused concealment into an all-rounder built for everyday carry, competition, and duty use. Much like the CCW variant, the Defender-ST is built to last — a durable aluminium optic body that's waterproof, shockproof, and fogproof, using high-quality glass for genuine clarity.
The DeltaPoint Pro footprint is one of the most widely supported mounting cuts on the market, giving you real flexibility across full-size and duty pistols. The larger 23mm x 20mm window is a genuine field-of-view improvement over the CCW, making target acquisition noticeably faster without sacrificing the compact profile that makes a micro red dot worth carrying in the first place.
Running on a CR2032 battery rather than the CCW's smaller CR1632, the ST delivers up to 25,000 hours of runtime — roughly triple the CCW's standard battery life — with 10 brightness settings (8 daylight, 2 night-vision compatible) accessed via a top-loading battery compartment that requires a specific tool for access, a genuine tradeoff for the improved sealing this design allows.

Which Micro Dot Optic Should You Buy?
Compare Vortex Pistol & Backup Dot Optics
| Model | Tier | Best Suited For | Weight & Battery Life | Noctis Verdict |
|---|---|---|---|---|
| Venom® Enclosed Micro Dot | Essential Level | First pistol dot on a genuine DeltaPoint Pro footprint, best price in this range | 50g, 20,000hrs | Best Value Entry |
| Defender-CCW™ | Professional | Concealed carry on sub- and micro-compact pistols — smallest, lightest option here | 27g, 9,500hrs | Best True Concealment |
| Defender-CCW™ Enclosed Solar | Professional | Concealed carry with dramatically longer runtime, still genuinely compact | 37g, 125,000hrs | Best CCW Battery Life |
| Defender-ST™ | Professional | General use — everyday carry, competition, and duty on a full-size pistol | 42g, 25,000hrs | Best Overall Balance |
| Defender-ST™ Enclosed Solar | Premium | Duty and competition use where exceptional battery efficiency and enclosed-emitter protection matter | 46g, 150,000hrs | Best Duty Battery Life |
| Defender-XL™ | Top Shelf | Competitive shooting — largest window and widest dot-size choice in this range | 55g, 25,000hrs | Best Competition Pick |
The genuine differentiator across this range isn't just price — it's window size, mounting footprint and battery technology. CCW uses the Shield RMSc footprint and is purpose-built for concealment; ST and XL share the DeltaPoint Pro footprint and step up window size and features; "Enclosed Solar" models use a completely different, heavier housing with a solar-assisted battery system, not simply a colour or dot-size option on the standard body.
Reticle & Sight Picture
The 3 MOA or 6 MOA bright red dot (a 3 MOA green dot is also available) gives you the same precision-versus-speed choice as the CCW, in a larger, faster-to-find window.
10 brightness settings — 8 daylight, 2 night-vision compatible — cover a genuinely wide range of shooting conditions from bright midday sun through to low-light duty and competition use.
