Mauser never made a profit on the normal commercial production run. They ended with a small profit that was mostly made on the commemorative versions.

Krieghoff tried a small production run a few years ago, ended up costing them about $10,000 a pistol. Norinco tried to produce a version a few years ago and also gave up.
