Description
The Geissele SD-3G is a flat-bow variant of the S3G, engineered specifically around the demands of 3 Gun competition. The pull is a deliberate hybrid, shorter than a traditional two-stage but retaining the staged break mechanics that keep a two-stage combat trigger safe and consistent under stress. Reset is fast. The flat trigger bow lowers perceived pull weight and gives the shooter cleaner tactile feedback on break, which matters when transitioning between stages at speed.
- Hybrid pull: shortened two-stage feel with single-stage speed
- Flat trigger bow reduces perceived pull weight and improves feedback
- Lightning-quick reset
- Total pull weight: 3.25 lb or 4.0 lb depending on spring selection
- Retains two-stage safety and robustness
The tradeoff with the SD-3G's tuned geometry and reduced pull is that it is optimized for competition, not general-purpose duty use. If your application requires a heavier, more deliberate pull for administrative or patrol environments, a standard two-stage like the SSA or SSA-E is a better fit.
What is the difference between the S3G and the SD-3G?
The SD-3G is built on the same internal geometry as the S3G but adds a flat trigger bow. That flat bow redistributes finger contact across the trigger face, which reduces the perceived pull weight and sharpens tactile feedback without changing the mechanical pull weight specification.
Which spring weight should I run?
Geissele ships the trigger with spring options that produce either 3.25 lb or 4.0 lb total pull. The lighter spring suits shooters who want maximum speed in competition. The heavier spring adds a margin of consistency in cold or wet conditions when fine motor control degrades. Verify compatibility with your lower before installation.
