Gas powered semi-automatic airgun action

A method of operating an airgun, the method comprising:

• receiving a pull force on a trigger, the pull force causing the trigger to pivot from a non-firing position to a fired position, wherein transitioning the trigger to the fired position:
• causes movement of a secondary sear,
• the movement of the secondary sear enables movement of a primary sear from a primary sear cocked position to a primary sear fired position,
• the movement of the primary sear to the primary sear fired position allows a hammer to move from a hammer cocked position to a hammer fire position, and
• the movement of the hammer to the hammer fire position causes pressurized gas to be released from a valve;
• and
• returning the trigger to the non-firing position under force of a trigger spring, wherein:
• a lift that is connected to the secondary sear is engaged with the trigger in the non-firing position and disengaged from the trigger in the fired position, and
• returning the trigger to the non-firing position causes movement of the lift, and reengagement between the lift and the trigger.

An airgun comprising:

• a hammer that, when transitioned from a hammer cocked position to a hammer fire position, causes pressurized gas to be released from a valve;
• a primary sear that is moveable relative to the hammer and configured to release the hammer from the hammer cocked position such that the hammer moves to the hammer fire position;
• a secondary sear that facilitates movement of the primary sear relative to the hammer;
• a safety configured to move between a safety engaged position and a safety disengaged position, the safety restricting the secondary sear from facilitating the movement of the primary sear while the safety is in the safety engaged position, the safety allowing the secondary sear to facilitate the movement of the primary sear while the safety is in the safety disengaged position;
• a trigger configured to move, against force applied by a trigger spring, from a non-firing position to a fired position;
• and
• a lift connected to the secondary sear, the lift engaged with the trigger in the non-firing position and disengaged from the trigger in the fired position, the lift facilitating movement of the secondary sear from a secondary sear cocked position to a secondary sear fire position when the trigger is in the fired position and the safety is in the safety disengaged position, wherein:
• a trigger spring is positioned to bias the trigger toward the non-firing position,
• movement of the trigger from the non-firing position to the firing position while the safety is in the safety disengaged position causes movement of the lift, and
• movement of the trigger from the fired position to the non-firing position causes reengagement between the lift and the trigger.
