Hybrid trigger for dynamic shooting
The Geissele SD-3G offers a smooth and rapid rolling action , inspired by the S3G mechanism. This hybrid architecture provides an ideal compromise between single-stage trigger pull and two-stage behavior, for fast and consistent engagement on dynamic shooting courses.
Flat tail: control and speed
The flat trigger improves control under the finger by reducing the feeling of weight at the start of the shot. This design ensures linear tactile feedback and appreciable consistency, especially in the rapid-fire sequences typical of 3-Gun or IPSC competitions.
Dual spring configuration
The SD-3G comes with two interchangeable springs:
- Lightweight spring: for an ultra-fast start of 3.0 to 4.0 lbs
- Standard spring: for a firmer feel, 4.5 to 5.5 lbs
All this within a non-adjustable mechanism but perfectly calibrated for high-level competition .

Can I use the SD-3G for precision shooting or shooting from a supported position?
No, this trigger is optimized for dynamic shooting. It is not recommended for long-range precision shooting.
Which spring should I choose?
The light spring offers a faster start (3 to 4 lbs), ideal for competition. The standard spring goes up to 5.5 lbs for added firmness.
