The Beretta 92FS appears to be the sidearm carried by the Military Police personal at Hawkins National Laboratory. The use of the pistol is anachronistic since the M9 pistol didn't enter U.S. military service until 1985, while the show takes place in 1983. It would be more accurate for them to be issued the Colt M1911A1 like the government agents. The majority of these pistols in the series appear to be replicas.

Note how these appear to be either dummy or airsoft replicas.
Jonathan Byers (Charlie Heaton) takes his father's Smith & Wesson Model 10 when he and Nancy Wheeler (Natalia Dyer) set out to find the monster in Myrkwood in "Chapter Five: The Flea and the Acrobat" (S01E05).

Her "golf club-style" grip seems unorthodox, but it's probably safe to assume that most high-school girls don't know how to properly hold a handgun. Despite this, she hits the can on her first shot.
Heckler & Koch MP5Ks with PDW stocks attached are also used by agents. Since the show takes place in 1983, this is considered anachronistic since the MP5K-PDW variant was not developed until 1991. Some of the stocks actually look to be UMP-style stocks, making them even more anachronistic.
When Will is running from the Monster in S01E01, he takes shelter in the shed and loads up what appears to be a Mossberg 42M that is missing the front portion of the Mannlicher stock.
