I remember them, though never had one. Ive only run across a couple for sale at gun shows (too highly priced for me) and no friends have had one, so never a chance to shoot one either. Thats too bad, as Ive read the ad copy in my old ('68?) catalog and thought they offered a lot of features in that time, and good, solid German steel & workmanship.
Of the few I seen, they were big and didnt fit my hand very well. As I remember, the grips seemed a bit too narrow at the top, but the bottom did flare out well into the palm and they were longer than a Colt's.
If one had come at the right price Im sure it would have been a dandy.
