S&W semi-auto model
So yo, the reason I identified it as a 639 was because of the lack of any kind of widening towards the rear end of the frame that would indicate a double-stack S&W model like the 659, 5903 or otherwise. I get your point about the patterning on the grips, but I'm not sure it's enough to identify the 5903 by itself. I think maybe the truth lies somewhere in-between these models.

- The wraparound grips are a strictly 3rd Generation feature - Earlier S&W autos like the 639 don't have them. There's also the Novak sights, which likewise weren't used on the pre-3rd gen guns (at least not that I'm aware). The blued controls (trigger and hammer) are also indicative, as they were used on later-made 3rd Gen stainless/alloy autos.
Having said that the gun is quite clearly NOT a 590x OR a 639, it's not nearly big enough in either slide or grip lengths and in the former case as noted (in a rather contradictory fashion) it also clearly lacks the frame bulge. This gun is - or at least best resembles - a 3913. StanTheMan (talk) 22:51, 2 August 2019 (EDT)
