I appears that your "19-8" is pinned & recessed. Could it be a 19-3?

The 19-8's were the last of the model 19's, made in the 1990's. They were not pinned & recessed. IIRC they had MIM hammers and triggers too. Your 19 has the better, and more attractive, forged case hardened hammer and trigger. The 19-8 came with Uncle Mike's rubber grips from the factory.

My guess is that yours is a 19-3. Perhaps with a sloppy roll-mark that appears to be an 8. It is also a round butt, which if factory original, adds to it's value.

The NIS ordered RB 19's, and the FBI SRT had them as well. Those banana grips themselves are uncommon and have gone in the classifieds here for $80 or more.

If yours is indeed a 19-3 factory RB, with original box and docs and those banana grips, it would bring $575 to $625 locally.

Very nice 19 you have. I'd keep it. They won't make them as nice as it again. Hope this helps! Regards 18DAI.

Edited to add: It appears your front sight insert is yellow. The NIS RB 19's had a yellow front sight insert. Do a search here for Naval Investigative Service model 19. You may be surprised by what you have there!
