Glock doesn't need to recreate a firearm to survive....
Not long ago a revolver rode on the policemans hip and 1911s on military personnel. Then Glock popped up. If you dont think a firearm can loose some thunder over the years, you're mistaken. Only thing keeping the 1911 and revolvers alive are collectors and old timers. It may take awhile but someone always builds a better mouse trap.
