Image Number 2 for United States Patent #5566488.
The pistol grip magazine adapter provides an insert for the magazine in the handles of hand guns. The insert is designed to fit snugly in the pistol magazine and is of a proper volume or density to reduce the space in the magazine such that only a single row ammunition clip will fit. The insert is attached to the inside walls of the magazine or is an element of the pistol grips. With the space reduction, standard single row clips holding up to ten rounds of ammunition may be inserted. However, the higher capacity clips, such as twenty rounds, for which the gun was originally designed will no longer fit. The inserts are formed from one or two pieces of material depending on the particular hand gun requiring the insert.
