Some muzzleloaders have a set trigger that allows the shooter to advance the trigger and set it so that very little additional pressure is required to fire.
There are three different set trigger designs.
- Single-Set: A single trigger. Push the trigger forward to set it. A gentle squeeze then fires the gun.
- Double-Set, Single-Phase: A two-trigger system. Pull the rear trigger to set the front trigger for firing.
- Double-Set, Double-Phase: A two-trigger system with two options. Pull the rear trigger to set the front trigger for a “hair-trigger” firing, or simply pull the front trigger for normal firing.
Once a set trigger has been set, you must make the shot or uncock before the gun is carried anywhere or left unattended, since the lightened trigger creates a safety hazard in those situations.
