A short time back I bought a used SS Taurus, I'm happy with it. It had a few burrs on the inside of the frame I removed ( didn't seem to affect function ), and like an above poster, I replaced the hammer and strut with Ed Brown pieces ( don't care for a "locking" system that could malfunction ). I lilke it. One thing I wish were different, it uses its specific extractor... I tried to get a replacement from Taurus ( just to have, didn't need it ), and they only had them in stock for their own use....maybe that will change. Other parts are, to the best of my knowledge, G.I.
