When Mr Sturm and Mr Ruger introduced their .22 Standard
semi-auto pistol in 1949 I don't think it a coincidence the outline looked familiar except for the toggle bolt. And it was named a "Ruger" (Luger) not a Sturm.
I've only owned one Luger, sold it and didn't look back. Same with the Walther P38's. All Nazi marked WWll. All inaccurate.
I only keep the shooters.
