Method of shooting a semi-automatic firearm

1. 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 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;
  
  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 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 comprisesslideably supporting the firing unit in a forward pointing direction by a handle for linear reciprocating movement relative to the stabilized actuator and the handle during said moving and said moving again steps, the linear reciprocating movement occurring along a constrained linear path generally parallel to the firearm barrel.
