The 39xx guns are a niche gun.

There are quit a few of us here who love it as a concealed carry weapon. I bought a couple over the years in the "real world" where most folks would trade them in for a Glock 19 or 26 because they have more bullets and was in the last action movie they've seen.

Collectible ???? Value????....... to paraphrase John Wayne in "She wore a yellow ribbon".... "maybe in forty or fifty years."

So my advice is clean it up, shoot it and carry it with a nice set of Hogue checkered wood grips.
