Have one that has been in the family for about 40 years. No it is not a real Luger, it's a fun to shoot pistol that is a pretty damn close copy as far as size & weight. You have to remember this pistol was engineered over 40 years ago, and sold for a whopping $60-70. They are a little ammo picky, but there are many .22's out there that won't function with just anything either. MIne likes CCI Mini-Mags, CCI SGB, Federal Auto Match, and WInchester. Most people who say they jam don't properly clean them. The toggle action comes out of the frame and is easily cleaned with aerosol cleaners like Birchwood Casey Gun Scrub.
I still have the factory holster that came with the gun, magazine charger, manual, and 2 mags. If you would like a photocopy of the manual just IM me & I will gladly mail you a copy. It has detailed instruction on stripping and proper cleaning; that toggle action needs to be cleaned periodically & lightly lubed to run properly. These guns came in 2 different barrel lengths, mine is the shorter of the two.
The toggle action is very fast, you can dump an 11 rd mag in literally 3-4 seconds with it's short light trigger. When I was a kid my brother and I would shoot it on our property and would see who could dump a mag the fastest
