I have shot in competitions since 1979 with only S&W revolvers, heads up against single shot and bolt actions in IHMSA, and semi autos in just about everything else. In order to be as competitive as possible, I have done tons of action work, built lots of custom guns and invented lots of parts and accessories.

My current project is a lockworks kit that makes the DA trigger pull get lighter as you pull the trigger back. The spring tension is adjustable for whatever primers you want to shoot. The current prototype will go from any starting weight down to around 4 pounds right before the hammer falls. The starting weight can be anywhere from 6 to 11 pounds.
