The following weapons were used in the film Murder At 1600:
Early in the film, Detective Harlan Regis (Wesley Snipes) has to talk down a bureaucrat who is threatening to commit suicide in the middle of an intersection with a stainless Taurus PT945.
Taurus PT945 .45 ACP (the one in the movie is an older model PT945, which has a stamped slide that looks slightly different)
A recently fired bureaucrat holds a Taurus PT945 on his own head and threatens to kill himself.
Regis picks up the PT945 after knocking out the guy.
Unknown flattop AR variant
In the opening scene of the film, a SWAT sniper is seen with an unknown AR-15 variant which has a flattop receiver with a scope, suppressor, and bipod attached.
The SWAT sniper aims his flattop AR15 at the suicidal bureaucrat.

Detective Harlan Regis (Wesley Snipes) carries a Gen 2 Glock 17 as his service weapon. All of the other Washington, DC police officers also use Glock 17s.
MPDC officers aim their Glock 17s at the suicidal bureaucrat after he has been knocked unconscious and disarmed.

Beretta 92FS Inox
Secret Service Agent Nina Chance (Diane Lane) carries a Beretta 92FS Inox as her weapon of choice throughout the movie, even though this weapon has never been approved for Secret Service use in real life.

Many of the Secret Service agents in the movie can be seen using SIG-Sauer P226 pistols as their sidearms, including Daniel Benzali as Agent Nick Spikings, the Chief of White House Security. It seems to be rather common for 1990s action movies to depict Secret Service agents using the P226 as their duty weapons (see also, for instance, Air Force One) even though in real life the P226 has never been used by the Secret Service.
There is an interesting scene in the film where Regis is forced to choose between two P226s when involved in a shootout, one of which is loaded and the other of which is not (he isn't sure which is which).

The ultimate dilemma: Two SIG P226s are in roughly the same place, and Regis has to choose the right one. One of them is Spikings' gun, which Regis knows he's already fired empty (and then stupidly hit the slide release), while the other belongs to the assassin he has just killed, and is loaded. They're the same type of gun, so he can't tell which is loaded and which isn't.

) with a P226.
Many of the Secret Service agents use Mini Uzi submachine guns whenever they are on alert, all of which seem to have their side-folding stocks removed for some reason. Although in real life, the Secret Service relied heavily upon the full version of the IMI Uzi (not the Mini version), the Service replaced it in 1995 with the Heckler & Koch MP5. Therefore, the agents should have been equipped with MP5s. When Detective Regis and Agent Chance are in a shootout in Spikings' house with assassins, one of the assassins is also using a Mini Uzi that has been fitted with a suppressor.

In the climax of the film, a Secret Service agent who captures Regis is armed with a Glock 26, another weapon which, like the SIG P226 has never been used by the Secret Service.

During the climax, at least one Secret Service Agent is armed with a SIG-Sauer P228, a pistol which was actually used by the Secret Service, unlike nearly all of the other handguns seen in the hands of the agents in the film.

When Regis goes to meet Kyle Neil (Tate Donovan), the First Son, he takes a Glock 19 off of Neil, but later gives it back.
Regis tosses Neil's Glock 19 back to him.
Some of the Secret Service Agents in the film use Beretta 92FS pistols, yet another weapon which has never been issued to the Secret Service. One of the assassins who fights Regis in Spikings' home also uses one.

Unknown AR carbine
During the shootout at Spikings' house, one of the assassins uses an unknown M16 carbine variant with a suppressor and Aimpoint sight which looks somewhat like an XM177E2, but this is not certain.
