A grip frame 21, preferably for a paintball marker, comprises a handle portion 22, having a cavity region 23 therein defined, a trigger 29 and an electronic/optical sensor (35, Fig 4a) which determines when trigger 29 has been activated. Grip frame 21 also houses an electronic circuit board 24 and a battery 25 and two adjustable stops which limit movement of the trigger in opposing directions. Trigger 29 is also urged back to a rest position by magnetic means. Upon activation of trigger 29, sensing means 35 communicates with solenoids 26 so as to fire and re-cock the marker. Display means 16, taking the form of multi-character LED or LCD displays, are positioned on handle 22 so as to face the user when the marker is being used. Calibration buttons 12, 13, 14 are also included. The intention of the disclosed invention is to allow the conversion of a mechanically operated paintball marker to an electro-magnetic one. Also disclosed is a paintball marker having optical sensing means positioned within the breech of the marker so as to allow any object positioned therein to be sensed.
