This is a genuine factory GLOCK 26 magazine designed to work in all previous versions of the GLOCK 26 including the new Generation 4. It features the double cut magazine body and will work if you have reversed your magazine release on your Gen 4 GLOCK 26. It also has a factory extended +2 base-plate which gives an increased round capacity as well as additional surface area to grip onto when the magazine is inserted in the firearm. The magazine is constructed from black polymer, and has a metal spring.
