Don't have the facts to go along, just an old and somewhat fallible memory, but the Contender went away and the G-2, notice even the name change, there was never a 'G-1', came to market. My memory says there were lawyers involved with some contention of the safety of the Contender and this lead to the loss of the principal's mfg. ffl. Doubt if you will ever hear Gregg Ritz mention it. The old Specialty Pistols forum is gone as is Magnum Mike, so all those file are lost in the ether. Since I'm not a lawyer, I am not well versed in researching old law files.
Since I didn't hunt with a Contender or carry one in a cross chest holster, I never paid much attention to the safety issue. My 'safety' is an empty chamber and an open breech, not good for hunting. The SSK does interest me and I'm thinking of owning one to go with my collection of Contenders. After all that ramble, I doubt that you'll never see a new Contender as T/C probably still/now owns the trademark and they wouldn't build one and probably wouldn't release the trademark.
Just 2 more of my pesos.
