Well, I handled a VP 70 years ago when I lived in Maryland. Local gun shop had one. I thought it was rather interesting looking and I always had a lot of respent for the H&K name. But geese, Louise! The trigger pull was something like 18 pounds! Yeah it can hold a gazillion rounds in the magazine, but most mere mortals would have terminally cramped trigger fingers after shooting a full clip from that thing.
Come to find out that this gun was really designed to be fired full auto, so most people would have pulled the trigger for a BURST, not a single shot at a time. H&K, for some off reason, just decided to make a semi-auto civilian version to sell.
Quite honestly, if someone GAVE one to me, I would just turn around and sell it for whatever I could get for it. I would never have any inclination to keep it, much less shoot it.
