from what I recall on them, was that they were decent guns, nothing super special or any main know issue's
there claim to fame was that the gun was used in the Miami Vice.TV show!
they had I think 3-4 versions of this model till they changed to a 4 digit model system, and then it became a 4 digit model, it had a few up grades, at this point too, but nothing I recall due to mechanical or safety issues with the original model!
just options and some fit and finish like deal!
I sold a few of them way back when, due to I think the TV show , more than any other reason LOL
i you like the gun, then the bidding is up to you, I don't think there is any big investment value in it, unlike the Bren Ten, the show started off with! before switching to this model!
but there will always be folks that collect things and willing to pay more for them!
