Moparmike:
Re Mauser and Mak, they serve different purposes entirely. Mausers are/were pretty decent, serviceable bolt action service/hunting rifles. Some of the "cheap" surplus 8mm (actually 7.92 x 57 mm) ammunition, particularly the Turkish is not only corossive, but high pressure, possibly higher than should be.
As for the MAK pistols, I have experience with the Russian make(9mm Makarov), not the .380, that ammunition is cheap too, and non corossive, for the most part. U.S. production is all non corossive. Trigger pulls are on the heavy side, not particlarly rough, just heavy, both single as well as double action.
The rear sight, adjustable, goes click, click when turned but movement is course, I suspect that this sight was used for it's ATF "point value". The Russian guns are or were reasonably priced, very reliable, though somewhat "rough" looking, and accurate enough for defensive use, and casual target shooting. For my eyes, (old), the front sight was much to small. That can be fixed by any competent gun smith.
Good luch.
