For: (Discontinued) KSC/KWA M26 Standard MagazineProduct Information:
First of all, this is a 16 round mag not a 19. It holds enough gas for about 22 rounds on semi and 16 on full auto. It also comes with a removable pinky extension grip. Its full metal construction. The only bad thing about this magazine is that the pin that holds the upper lip in place falls out if your not carefull.
overall great buy.
