The Infinity release trigger, built to last, machined from 1045 carbon steel material. All the sears and main trigger parts are heat treated S-7 Tool Steel. Oversized pin for years of service. The design is simple and little to no maintenance required. Two parts switch the unit from a release to a pull trigger. One housing for everything. 
And the best feature is no up-charge when buying the gun with a release trigger.
