I bought a PT 24/7 PRO LS (longslide) about a month ago. It is black frame, ss slide. Mine is in 9mm, came with 2 17 round mags. When I entered my serial number on the Taurus web site, it accepted it but also said there was no information on it. When I mentioned this to my gun dealer he tried to look it up, and could not even find in his books. He thought that maybe it was a gun sent to him by his distributor as a promotion. Love the look and feel of this gun. I am having some problems with it but I plan to have them all worked out, sure plan to keep it.
