I'm talking about the red dot that appears in the back of the slide when the HK VP9 is cocked. I see that it already existed in the Walther PPS and I assume that H&K took it from the Walther, but wondering it originated in the Walther or if it goes beyond that to another gun.
Any information on the origin of that feature is appreciated.
