Product Features
Improves control and visual tracking on subcompact pistol
Struggling with a tiny window on your slimline carry pistol? Upgrade to a competition-style large window optic with a crisp, easy-to-track dot for faster target acquisition, smoother follow-up shots, and a more confident shooting experience!
A Bigger Window for Slimline Pistols
A compact pistol should not leave you searching for the dot. The GP-3 gives compatible RMSc setups a 25.4 × 19.8 mm viewing window, making it easier to pick up the reticle as you present the pistol and keep it in view during follow-up shots.
At 41 g (1.45 oz), the optic balances that larger sight picture with a size suited to everyday carry. It is equally at home on a range or competition setup where quick visual tracking matters.
3 MOA Crisp Green Dot & Astigmatism-Friendly Aspheric Lens
The 3 MOA green dot offers a practical balance of visibility and precision. Its aspheric lens is designed to reduce visible distortion across the viewing area, helping you maintain a clear view of the target.
If traditional dots appear blurred or starburst-shaped to you, the GP-3’s lens and green reticle may be worth considering. Astigmatism affects each shooter differently, so the dot’s appearance is best judged with your own eyes.
Prefer a red aiming point? Explore the GP-3 Red Dot Sight with the same large-window and aspheric Lens design.
Industry Standard RMSc / K Series Footprint
The GP-3 uses an RMSc-style mounting footprint and is intended for compatible optic-ready slides or mounting plates. Its low-profile design may allow use with iron sights on suitable pistol setups; the sight picture depends on the slide and sight height.
Motion Activation Technology
Protective Button Guard
The button shield prevents accidental presses, so you can operate with confidence without unintended adjustments.
Side-loading Battery Compartment
Side-loading battery design allows quick battery replacement without removing the optic, and keeps your zero perfectly intact.
Rugged Construction
The GP-3 uses a 7075-T6 aluminum housing and is listed with IPX7 water resistance and a 1500G shock rating. It is designed to stand up to regular carry, range sessions, and changing weather while maintaining a dependable aiming point.

FAQ
Is the GP-3 designed for everyday carry?
Yes. At 41 g (1.45 oz), the GP-3 is lightweight enough for compatible compact and slimline pistol setups while offering a larger 25.4 × 19.8 mm viewing window. Please note that the larger window may not fit some holsters, so check holster compatibility before purchasing.
What is the advantage of the larger window?
The larger window gives your eye more room to find the dot when presenting the pistol. It also makes the reticle easier to track during follow-up shots and target transitions.
Will changing the battery affect my zero?
No. The side-loading battery compartment lets you replace the CR1632 battery without removing the optic, so you do not need to disturb its mounting position.
Is the GP-3 suitable for shooters with astigmatism?
Its astigmatism friendly aspheric lens is designed for a clear sight picture, but no optic can guarantee a perfectly round dot for every shooter. Perceived dot shape depends on your vision.
Is the GP-3 waterproof?
Yes. The GP-3 has an IPX7 water-resistance rating and is designed for use in rain and wet outdoor conditions. Close the battery tray securely before use.
