T.H.E. Accessories Mag Release Assembly, Chevron Serrations, for Glock 10mm/.45, Black Aluminum

This part is a must have and should be standard on all glocks from the factory. The fact that I had to spend the extra money on this was irritating. If this part was standard on all glocks from the factory than the Springfield XD and the Smith and Wesson M&P''s wouldn''t be able to compete with the glock.
