An evolved version of the distinctive Vortex Defender red dot sight, this time designed for duty pistols. It is therefore larger and slightly more substantial, but most importantly remains extremely durable and well suited to the tactical character of the firearm. The objective has been proportionally enlarged to provide a wider field of view and a broader zero-adjustment range. Combined with a classic 3 MOA dot, it is an excellent choice for tactical and dynamic shooting. The 6 MOA version, meanwhile, is ideal as an addition to a duty pistol or a model used privately for personal protection. Pistols are not the only option for the Vortex Defender-ST - thanks to the Picatinny mount included in the set, it can also be used on a shotgun or PCC carbine.

Features of the Vortex Defender-ST red dot sight:

• MRDS sight designed for duty firearms
• durable construction based on anodised 7075 aluminium
• button lockout function to prevent accidental changes to settings,
• large aspherical lens providing a clear image across the entire surface,
• optics protected by a hard Armortek protective coating,
• Shutoff automatic power-off system extends battery life,
• true 1× magnification with no parallax error,
• motion activation provides instant readiness,
• popular DeltaPoint Pro footprint,
• Shocksield polymer insert protects against everyday damage,
• Fast-Rack - textured surface that increases grip when racking the slide,
• 12-level dot brightness adjustment (10 + 2 NV).

Vortex Defender-ST - the ideal MRDS red dot sight for a concealed-carry pistol

The sight body is precision-machined from 7075 aircraft-grade aluminium. This gives the unit a lightweight yet durable construction weighing just 41 g. The aluminium body is finished with hard anodising for high resistance to abrasion and scratches. The sight base uses the popular DeltaPoint Pro standard, eliminating the need to purchase an additional mounting plate or have the firearm modified by a gunsmith.

The front of the sight features aggressive Fast-Rack serrations, allowing the pistol slide to be racked securely using the sight itself. The sight has a waterproof and dustproof housing, supported by a polymer Shockshield insert that effectively absorbs impacts and firearm recoil. The narrow profile helps the pistol draw smoothly from under clothing while allowing discreet carry. The sight has a simple, user-friendly interface operated by large buttons positioned on both sides of the housing.

Vortex red dot sights with a lifetime warranty — red dot sights for pistols, sport shooting and defensive applications

The Vortex Defender-ST features a high-quality lens with multi-layer anti-reflective coatings that provide high light transmission and a clear, sharp image free from parallax error. The sight stands out not only for having one of the largest lenses in its class, but also for the aspherical profile of its optics. This provides crystal-clear sharpness not only in the centre but also around the edges. The result is a bright, clear view of the target and comfortable use even in low-light conditions. With 3 dot variants (3 MOA red / 3 MOA green / 6 MOA), you can match the sight to your shooting style:

• 3 MOA red dot – precise shots at longer distances, ideal for static targets.
• 3 MOA green dot – a versatile solution combining accuracy and speed, ideal for dynamic shooting.
• 6 MOA red dot – a versatile solution combining accuracy and speed, ideal for dynamic shooting.

The aiming point has a click value of 1 MOA and can be adjusted over a range of 115/145 MOA (horizontal/vertical). The hard Armortek coating protects the lens against scratches and other external factors.

The control system and LED are resistant to firearm recoil and weather conditions, allowing the sight to operate reliably and efficiently even in demanding field conditions. The sight is powered by a CR2032 battery which, according to the manufacturer, provides up to 25,000 hours of operation at brightness setting 6. As on the Venom model, the battery compartment is located on top of the unit, allowing the power source to be replaced quickly and conveniently without removing the sight from the firearm. The user has 8 daylight settings and 2 night-vision-compatible settings. Extended operating time is aided by a motion sensor which, after 14 hours without movement, automatically switches off the LED and puts the sight into sleep mode. To reactivate the sight, simply pick up the firearm. The motion activation system wakes the sight instantly, so it is ready to use immediately even after being stored for an extended period.

The Vortex Defender-ST set includes:

• Picatinny mount,
• rubber cover,
• optics cleaning cloth,
• CR2032 battery,
• sight adjustment tool,
• set of 6 mounting screws.
