We had a Sphinx AT2000S 9mm as a range gun in our club with the threaded barrel. 100% swiss quality, very tight slide and frame fit, very reliable, very comfortable grip. It was a beautiful piece but I never liked the "feel" of the SA trigger...
WESHOOT2:The Tanfoglio, the EAA Witness (=Tanfoglio), the IMI Jericho (Baby/UZI Eagle), and the Sphinx are all CZ75 copies. Only the Sphinx has SIG-Browning locking system.
