The Super Dynamic (SD)triggers have the same body geometry as the SSA models and feature a flat trigger shoe that reduces perceived pull weight, improves control, and gives excellent tactile feedback. Super Dynamic Combat (SD-C) trigger has a 2.5 lb. first stage and a 2 lb. second stage for a 4.5 lb total pull weight with a sharp, repeatable trigger release. Super Dynamic Enhanced (SD-E) trigger has a combined 3.5 lb. total pull weight, with a 2.3 lb. first stage and a 1.2 lb. second stage. Super Dynamic 3-Gun (SD-3G) single-stage trigger has 3.5 lb. pull weight with a short pull length and short reset - excellent for fast-action competitions.
