Bought a hand-picked Yugo several months ago. Left it in the box for a couple months after looking it over and working the cosmo-coated action.
Finally cleaned off all the goop, to discover that the trigger took 3 pulls to drop the hammer. Gunsmith check indicated that the gun was a Frankenpistol, assembled out of a parts box, and the parts didn't fir quite right. Called SOG; they saif they had a 30 day warranty, long expired, but they'd look into the situation. Next day said to send it back.
So I did. (Pity, the thing looked unused. Of course, it was never used, just spare parts. BTW, the safety, which of course was an add-on due to import restrictions, was so tight as to be nearly unusable. I attribute this to the pistol's origin as a random selection of parts, assembled by an importer). Got a replacement in a few days, which seems to function properly, though it has yet to see the range.
Personally, I think they should have sent me a couple drop-in hammer units to see which one worked; would have saved a lot of shipping hassle and paperwork. On the other hand, I can see that they had a crate full of pistols assembled by the importer; from their point of view it was much simpler to just swap pistols.
This was my first experience with one of the big surplus outfits using my new C&R. I have to say that dealing with individual sellers and small dealers has been rather more successful.
Magazines for the Yugo Tokarev are hard to find, which may be a consideration.
