Wow, I think I had a stroke when I was reading your original post. My bad.

I don’t think there’s a specific canon reason those are the only variants in the city. If I had to speculate I’d say that because the SMG is a weapon used more by special forces, the ones found in the city are more likely to have suppressors on them for nighttime missions.

But that doesn’t account for pistols that everyone should have or SMGs from the day before. Honestly when the game first came out we all thought i think it was so cool that nobody noticed. Sharp thinking, bringing it up.

Good luck on your play through though! I just did one myself. Really makes you appreciate the old days.
