The most prominent weapon in the film, the Spectre M4 SMG is used by Valkenvania Police Chief Constable Dennis Valkenheiser (John Candy), and Constable 'Miss Purdah' (Valri Bromfield). All the Spectres in this film have the foregrips and folding stocks removed.
The drunk crook Arthur (Daniel Baldwin) pulls a Snub-Nosed Revolver of unknown Make and Model on Dennis, though it gets quickly knocked out of his hand. It is seen again a bit later in the courtroom on the desk of Judge Alvin Valkenheiser (Dan Aykroyd).
As Judge Alvin Valkenheiser examines the confiscated items, including the revolver shown above, what appears to be a Beretta 92SB semi-auto pistol can be seen to the upper right.
Miss Purdah carries and fires a Ruger Mini-14 rifle with scope and stainless barrel/reciever at Chris and Diane as they escape the Valkenhesier Salvage towards a train.

Mossberg 500AT
When Chris and Diane have the State Police raid the Valkenheiser Salvage near the end of the film, some of the troopers carry what appear best to be standard Mossberg 500AT shotguns (wooden furniture), which I figure mainly because of the dual-action bars.
