If the 356TSW was first made in a 5" in 1993, you would think the 9mm Target Champion would have soon followed as only a barrel would be needed to create a different gun.
In 1997 the NRA advised they would be offering a separate 1500 Semi Auto open match at the Police Nationals in Sept. Before that, officers shot the Distinguished auto match and the stock/service auto matches, but no one took it too seriously and shot the distinguished match, usually with someone's borrowed bullseye gun and whatever service auto you had.
Then around May/June 1997 ?, S/W sent four of their new "PPC" autos, a Target Champion fitted with aristocrat sights, to the top 4 of our team members. These guns, I am almost positive had "WISCHO" serial numbers. They sent us a bunch of "Target Champion" t-shirts also, I probably still have one in my shooting shirts. I did not get one of the original guns, so I immediately ordered one. I received it the first part of Sept, just in time to practice a bit before Nationals. I swear I think it had a PCV serial number. Will try to look it up. We also received several of the 4" DPA guns at the same time, 97 August/ Sept. I did get one of those XXX018 and still have it. So, both of those guns came out in 1997, positive.
They were big hits at the Nationals and by the next year most shooters had one. My wife got one in 9/98. By then it had a PPC # 0225. Some years later I sold mine and kept hers as it was in better shape and was more accurate. She had graduated to a 6" PPC.
We did promotional work for S/W and at the Shot Show in 1998 I was told by the S/W attorney there or Tom Kelly of the P/C, I can't remember who exactly. That the agreement with WISCHO to market the Target Champion in the US as the PPC-9 was that it would only be available to LE. I guess that was to protect their interest. The gun with the sweep upward, hammer block type safety really doesn't lend itself to action pistol type shooting. But for PPC competitors at the time it was a blessing at $800.00 or so for a great shooting 9mm semi auto. There was nothing priced close that could compete with it. Custom 1911s were about double that or more for 50 yard accuracy.
I hope this sets up a timeline as the TC was not marketed here at the time of the PPC 9s, unless it was much later.
