I had three STOEGER stainless Aimco Lugers, and all three of them had problems. The metal was not hardened properly, you could see the toggle battering on the frame rails which were indented at the impact point and mushed out on the sides. The parts were similar but not to the exact fit, nowhere as close as even Erfurt parts are to DWM. None of the three guns would shoot two rounds in succession without stovepipe jams etc. Their magazines are completely different from Luger magazines.
Besides that, I was put off by the wavy buffing and melted edges everywhere. Even a beater German P08 beats a Texas stainless copy.
If you have to have a white metal Luger, take an old mismatched and badly refinished German Luger, and strip it (with chemicals). Just keep it oily.
