A handle assembly and combined interface system for use with a semi-automatic firearm to facilitate controlled bump firing methods. The handle assembly includes a finger rest for the user's trigger finger. The interface system is attached to a receiver of the firearm, and is slideably disposed in the handle assembly for reciprocation. In use, the user pushes a firing unit portion forward with an opposite hand so that its trigger collides with the user's finger, thus stimulating a round of ammunition. Recoil forces the firing unit rearwardly so that the trigger separates from the finger. The user then applies another forward activation force that urges the firing unit forwardly again to repeat the cycle for as long as the user chooses. A lock can be selectively engaged to restrict longitudinal movement of the firearm relative to the handle, thereby returning the firearm to normal semi-automatic functionality.
