Bump fire grip

摘要

A pistol grip that assists in bump firing a pistol is disclosed. The bump fire grip may comprise a partially hollow exterior shaft that can contain an interior shaft. The interior shaft can be sized to slide from the front to the back of the exterior shaft, and vice versa. The interior shaft can slide on one or more pins, wherein the pins are lockedly engaged in the exterior shaft, pass through the interior shaft, but are not attached to the interior shaft. The bump fire grip can also employ a male/female grove design such that male groves on the exterior shaft can receive female groves on the interior shaft. The interior shaft can slide on the male/female groves. The bump fire grip can also include a locking mechanism, which, when engaged, can prevent the interior shaft from sliding within the exterior shaft, prohibiting bump firing.
