The method of firing a paintball marker uses a grip frame 21 replaces an existing grip frame 1 on a paintball marker in order to convert said paintball marker from a mechanically operated paintball marker into an electro-pneumatic paintball marker. The electronic grip frame 21 utilises an optical sensor in order to detect the operation of a trigger 29 and a second optical sensor to detect the presence of objects within the breech of the paintball marker. Electrical signals from these sensors are taken to an electronic circuit board 24, which controls the operation of two solenoids (one shown 26) in order to fire and re-cock the paintball marker. A user interface comprising pushbuttons 12, 13, 14 and a multi-character display 16, allows the user to define how the grip frame 21 functions.

What is claimed is: 1. A method of firing a paintball marker, comprising the steps of: providing a frame; providing a trigger, having a front side and a rear side and being rotatable about a pivot axis, pivotally connected to the frame; connecting a prong to and emanating rearwardly away from the rear side of the trigger; mounting a light emitter, capable of emitting light, to the frame; mounting a light detector to the frame and positioned in parallel spaced apart relationship to the light emitter defining an elongated passage therebetween having a longitudinal centerline; the light detector being capable of detecting light emitted from the light emitter transversely through the elongated passage; moving the prong along the longitudinal centerline between a depressed firing position between the light emitter and the light detector and a released non-firing position not between the light emitter and the light detector; the light emitter and the light detector forming an optical sensor; moving the prong along the longitudinal centerline upon rotation of the trigger about the pivot axis; providing an electrical output connected to the optical sensor; generating a first electrical signal indicative of the trigger at the released non-firing position where light from the light emitter is directly detected by the light detector; generating a second electrical signal indicative of the trigger at the depressed firing position where the presence of the prong in the elongated passage prevents light from the light emitter from directly being detected by the light detector; depressing the trigger; sensing movement of the trigger to a depressed firing position; and sending the second electrical signal indicating that the trigger is present in the depressed firing position. 2. The method of claim 1, wherein the frame and trigger are made of metal. 3. The method of claim 1, wherein the frame and the trigger are made of plastic. 4. The method of claim 1, further comprising the steps of: providing a microprocessor electrically connected to the electrical output of the optical sensor; providing a sear solenoid electrically connected to the microprocessor; providing a hammer mechanically connected to the sear solenoid; providing a pin valve, with a pin, mechanically connected to the hammer; providing a source of gas fluidly connected to the pin valve; providing a breech connected to the frame; providing a paintball in the breech; sending the electrical output of the optical sensor to the microprocessor; initiating a firing cycle; energizing the sear solenoid for a predetermined amount of time; releasing the hammer; impacting the hammer into the pin of the pin valve; releasing the gas through the pin valve into the breech; and propelling the paintball.
