bottom is for sure a makarov, may be a 9x18 or may be a 380. Only a mm difference in shell casing length between the two. Whoever it was that is talking about how well respected and stuff glocks are, yes and no. They aren't nearly as high quality as they once were. More often than not department are getting away from the glocks and going with H and K for it's fairly affordability or Springfield Armory because they are the shit.

EDIT: Not claiming to be an expert, but I carry a Smith and Wesson .40 and Remington 870 Magnum every day, so I know a little bit about duty carry fire arms.
