I have two. One will probably be forever unobtanium due to crazy price and scarce availability. The other is just expensive and would do nothing aside from put a grin on my face every time I pulled the trigger!
German MP44 (Sturmgewehr 44) my grandfather carried one during his Uncle Sam sponsored European vacation in the mid 1940’s. He carried it during guard duty and one night a superior officer who had been out drinking didn’t want to give the answer to the challenge question my grandfather asked him. When my grandfather racked that bolt the answer came quickly. Shortly after it was strongly suggested he carry his issued rifle while on duty and turn the MP-44 in to his CO never to be seen again. No way to know what ever happened to it but every time I see one I think it could be the one he carried.
Desert Eagle .50 AE. Just because.
