If they are Yugo Model 57s, I strongly urge you to grab yourself one. The TT-33s that had to have those kludge-safeties installed before they could be imported are nowhere near as good as the Model 57s. They have the same controls as an M1911. i own one, and my only complaint about it is the spare magazines are difficult to find, though Wideners has them at a price that will make you only grumble, not kick holes in the wall. They are great-shooting guns!
