What was the first year(?) that the M-19 used some mim parts? I'm not sure, but the -5?
Thanks

1996 with the thumbpiece. It was during the -7 change.

Thanks, snw19. I had a chance to pick up a -5, and I wanted to be sure. Not that it would be the unpardonable sin, but I want to stay with the tried and true. (will be questioned by some)
It is a great condition six inch with everything original. I'll be paying too much I'm sure, but I have a M-66 and want to add this one to my shooters.
