I'll record the data in an appropriate section related to the Steyr Hahn. I had assumed that the problem was light bullets 115s, as the old Luger 08 standard version of this cartridge -- the original version -- was loaded with 124 grain bullets, and I'd found that my 1912 ran flawlessly with Remington 124s, but jammed with Win "white box" 115s. I'll have to do some tesing to confim, but it looks like the thinner case rims of the Win brass allow enough slop in the extractor bite to let the extractor pop off the casing -- resulting in failures to extract. The extractor is un-damaged and the bolt face has not been altered. I now wonder if the reason why the Luger P.08 pistol is finicky about ammo might be essentially the same. Unfortunately, the Lugers are now prohibitively expensive. The collectors drove values for the good ones through the roof, then bought up all the shooter grade Lugers so they wouldn't have to fire their safe queens, and so for decades even the worst junker Lugers, when you can find them, are about as much bucks as a new Glock. I had a mis-matched Luger for a while, but parted it out to sell after realizing that if I continued to attempt to make it run right, the parts were going to run my investment so high that I'd be better off buying a better gun. Oddly enough, I sold off most of the parts of that gun very quickly and made more money off of them than I'd invested in the whole gun.
So -- the upshot is that I don't have a Luger to test fire. And while I'm on the topic -- the Luger is a good example of a gun being sought after largely because it's sought after. It's kind of like Paris Hilton -- famous for being famous. The guns themselves are unecessarily complex and expensive to produce, have very poor placement of their safety levers, don't tolerate fouling and nasty battlefield conditions terribly well, and require a small, fussy, and easily lost tool to load their magazines. Once an officer had fired his two mags through his Luger, he'd probably need to sit down and take a bit of quiet time out to reload. But they are sexy looking, have a fascinating history, and great appeal to fans of mechanical design.
