A magazine grip extension replaces the magazine base plate increasing the total length of the magazine. Increasing the total length of the magazine provides for extra grip length which in turn stimulates superior control and comfort. This magazine base pad was developed to fit the generation 3 Glock subcompact models. The texture and fit matches the generation 3 Glock models perfectly. This product will fit generation 4 Glocks and increase capacity of the magazines but the checkering pattern will not match. DISCLAIMER: This product is not manufactured, authorized, endorsed, or warranted by GLOCK. GLOCK does not warrant or represent that this product is compatible with GLOCK pistols.
