I don't own one, but I've read nice reviews.
I've seen a couple references in this thread about it being a clone of something else, I don't think that's the case: what I've read is that it has a unique barrel action. Supposedly leads to very smooth recoil, and the guns are well-made.
I think you might have an issue getting parts, but that tends to be an overrated concern, I have quite a few surplus pistols that have been shot a lot, both before and since I've gotten them, and I've never needed "warranty coverage".
Do a search in a couple places: ebay, gunbroker, numrich, wolff springs, etc.
If you can find a couple of firing pins and extractors, and Wolff has springs, I think you're as covered as you need to be for repairs.
Re magazines, check around and see if there are any compatible mags. it might share mags with another gun, if it does you're good. You might find that it has the same dimensions, but a different notch (I have a gun that will fit Beretta mags, but the notch is different); a little dremel work and again, good to go.
