Method of shooting a semi-automatic firearm

A method for firing multiple rounds of ammunition in succession from a semi-automatic firearm, said method comprising the steps of:

• providing a semi-automatic firearm receiver for chambering a round of ammunition, a barrel extending forwardly from the receiver and a trigger configured to selectively stimulate a round of ammunition disposed in the receiver, the receiver and barrel and trigger being moveable together as a firing unit;
• loading a first round of ammunition into the receiver;
• placing a user's first body part in operative relationship with the firing unit so that movement of the first body part causes a corresponding movement in the firing unit;
• stabilizing an actuator in a stationary position relative to a second body part of the user so that the firearm trigger will intermittently collide with the actuator in response to linear reciprocating movement of the firing unit;
• moving the user's first body part relative to the second body part using only human muscle power to generate a primary forward activation force urging the firing unit forwardly so that the trigger collides a first time with the stabilized actuator;
• stimulating the first round of ammunition in the receiver in direct response to said moving step, said stimulating step including discharging at least a portion of the first round of ammunition from the receiver into the barrel, said discharging step including generating a recoil force sufficient to cause the firing unit to translate rearwardly relative to the stabilized actuator, separating the trigger from the actuator in direct response to the recoil force by at least a predetermined distance (D);
• automatically self-loading a second round of ammunition into the receiver in response to the recoil force;
• then moving again the user's first body part using only human muscle power to generate a secondary forward activation force urging the firing unit forwardly relative to the stabilized actuator by the predetermined distance (D) so that the trigger collides a second time with the stabilized actuator;
• repeating said stimulating step with respect to the second round of ammunition in the receiver;
• wherein the improvement comprises
• slideably supporting the firing unit in a forward pointing direction by a handle so that the firing unit is capable of reciprocating linear movement relative to the handle, and restricting access of the actuator to the trigger during said moving and said moving again steps until the firing unit moves forward relative to the handle by at least the predetermined distance (D).
