Founded on a culture of innovation and robustness, Geissele Automatics has been developing high-precision triggers and components for civilian users, competitors, and specialized forces since 2004. Renowned for the quality of its triggers and its reliability in extreme conditions, the American brand has established itself as a global benchmark.
Extreme responsiveness for dynamic 3-Gun sport shooting.
Designed for competition, the Geissele SD-3G offers an ultra-fast hybrid trigger pull, combining elements of a single-stage and two-stage trigger. With its straight tail and ultra-short travel, it allows for precise and rapid follow-through, ideal for 3-Gun or dynamic shooting. This model retains the mechanical base of the S3G, with modernized ergonomics and enhanced performance.

The Geissele SD-3G is designed for one thing: speed. Engineered for 3-Gun shooting, this hybrid trigger offers a smooth break with instant reset, while retaining the safety of a robust two-stroke-type mechanism.
Hybrid trigger for dynamic shooting
The SD-3G's firing profile falls between a single-stage and a two-stage trigger, with a progressive break and extremely rapid return. This unique behavior offers great smoothness in rapid fire, while remaining predictable.
Flat ergonomics for greater control
Its flat trigger provides a linear feel, reduces the perceived trigger pull weight, and improves tactile feedback with each shot. In use, control is immediate and intuitive.
Performance calibrated for competition
Designed for fast-paced events, the SD-3G offers two configurations:
- 3.0 to 4.0 lbs with the light spring
- 4.5 to 5.5 lbs with the standard spring
This is not a trigger for long-range precision shooting, but it excels in fast engagements, IPSC courses or 3-Gun events.
FAQ
Is the SD-3G trigger compatible with all AR15s?
Yes, this trigger is compatible with AR-15 and AR-10 platforms equipped with Mil-Spec pins. No additional milling is required.
Can I use the SD-3G for precision shooting or shooting from a supported position?
This model is not designed for precision shooting. Its very fast trigger pull and short reset are optimized for dynamic competition, not for grouping shots at a fixed target.
Which spring should I choose?
The light spring offers a starting resistance between 3 and 4 lbs for maximum responsiveness. The stiffer spring goes up to 5.5 lbs for those who prefer a little more resistance under the finger.
