TFP4369, 1992 Quantico is what S&W folks told me, no dots under the decocker, this gun was in the run after the refit and the slide is marked "capable of firing with magazine removed"
I sent this gun back to S&W last year and had it gone through, Vito did the work. Nice shooter, pretty much my everyday carry piece. I do need to get the sights relit or replace with some MMC adjustable target sights
I sure would like to get my hands on at least one of the high cap mags
