Abstract: The present invention defines a system (200), comprising various structures and methods, for increasing the effective grip area of a compact or sub-compact pistol (100) in a secure, yet easily removable manner. A base collar portion (202) is provided, having a magazine channel (214) formed through it. The base collar portion is adapted to securely connect with the bottom (218) of a desired pistol grip (102). An engagement shaft (204) is disposed along the along the base collar portion. The engagement shaft is adapted for insertion into a corresponding cavity (110) within the desired pistol grip—usually along a backstrap portion of the desired pistol grip. The engagement shaft secures contact between the base collar portion and the desired pistol grip once fully inserted into the corresponding cavity.
