Yes, I remember something about the G11 ammo being a major probelm, which is another reason I find it hard to believe that this weapon would have been fielded. It wouldn't be a good idea at the height of the cold war to try to produce a ammunition that only one or two company's made. It's not a great idea that both those company's are in Germany eithier, which could have red tanks pulling up in the parking lot in a short amount of time.
But, still why do all that research and development to just throw something away? Why not sell your product to law enforcement? HK just does dumb shit sometimes. They tend to snub the civil American market, which doesn't make sense eithier. I think they just have a history of bad marketing. HK may have thought they were going sell their gun, but that doesn't mean the military really thought they where gonna buy it.
As for the G41 if it was that much more then the G36, I could buy that. Again though why not sell it to the civilian market? Their are enough HK fans out there that will pay unreal prices for there stuff, but the company fails to see or really care.
Sometimes people have great hopes of selling their gear and shit falls though. The same thing happened with the Thompson submachine gun. Thompson thought he had a winner.But, it was deemed to expensive and really didn't get any major sales until WW2.
