Nah. I’ve never had a Luger jam as long as it was good quality ammo and the action was oiled. The trigger is atrocious and it takes a gunsmithing genius to give it a decent, creep-free pull - but Lugers are accurate and dependable pistols. Maybe you had a bad magazine or your Luger was a “parts” Luger.
Talk of Lugers always reminds me of this sorry episode.
