Freeze (Reginald E. Cathey) is seen armed with a Glock 19 during the failed bank robbery. Several of Niko's (Orestes Matacena) thugs during the shootout in the Coco Bongo club are also seen with G19s, one of which has a chrome slide.
Dorian Tyrell's (Peter Greene) sidearm in the film is a Star Firestar M-43 9mm with a nickel finish, which he uses to shoot at Ipkiss/Mask (Jim Carrey) in the Coco Bongo club.
Niko (Orestes Matacena) draws a chrome Jericho 941 R to defend himself during the shootout in the Coco Bongo club. Since Dorian (Peter Greene) is wearing the Mask, he allows Niko to shoot him several times, which has no effect on him. He then sucks up the bullets and fires them out of his mouth, killing Niko.
When Niko (Orestes Matacena) plays golf off of Dorian Tyrell's (Peter Greene) mouth, one of his henchmen forces him to stay still by holding a heavily customized Colt MK IV Series 70 (which can be noted by its stamp on the slide) on him. The gun's features target sights, a commander hammer, ornate grips, a beavertail grip safety spur, and a sight rib. The gun is not a Colt Gold Cup National Match as previously suggested, note how the cocking serrations are completely vertical (instead of slanted like a GCNM).
When Ipkiss/Mask (Jim Carrey) imitates a cowboy while under fire from Dorian (Peter Greene) and Orlando (Nils Allen Stewart) in the Coco Bongo club, he is seen with a pair of nickel Single Action Army revolvers, one of which is shot from his hand.
Some of the Edge City Police officers use Smith & Wesson Model 10 Heavy Barrel revolvers. When Stanley Ipkiss (Jim Carrey) escapes from jail, he steals an officer's Model 10HB and uses it to force Lt. Mitch Kellaway (Peter Riegert) to take him to the Coco Bongo club, where he is later disarmed of it by Orlando (Nils Allen Stewart).
When a group of street thugs attempt to rob Stanley Ipkiss (Jim Carrey) while he is wearing the Mask, he makes several balloon animals to humor their stupidity before building his "personal favorite", an M1928 Thompson.
Trivia: This scene is one of the few, that came from original "Mask" comic books. In the comics M1928 Thompson was one of the weapons used frequently by Mask.
Edge City SWAT officers use Colt AR-15 A2s (also called the Colt Government Model HBAR, the civilian version of the M16A2) when trying to arrest Mask/Stanley Ipkiss (Jim Carrey) outside the park.
Mrs. Peenman (Nancy Fish) uses a Mossberg 500 shotgun to shoot at Stanley Ipkiss (Jim Carrey) when he first puts on the Mask and wreaks havoc in her apartment. Lt. Mitch Kellaway (Peter Riegert) tells Ipkiss that she fired a couple of rounds of "20-ought-buck", which makes no sense as there is no such thing.
How else could you describe these? After being barraged by a hail of gunfire, Mask/Stanley Ipkiss (Jim Carrey) shows the thugs what he's packing (after doing his spot on impersonation of Clint Eastwood), which happens to be guns and more guns combined into one gun. After the thugs flee in terror, he reveals they are all "bang" flag guns.
Using the power of the Mask, Dorian Tyrell (Peter Greene) allows Niko (Orestes Matacena) to shoot him several times (which he shrugs off) and then sucks up the bullets and fires them from his mouth. Since his mouth isn't actually a firearm, this was added to mainly reveal some goofs present.
Error creating thumbnail: File missingEven though he was shot several bullets, he manages to have whole cartridges in his mouth. A show of the Mask's ability to bend reality.Error creating thumbnail: File missingDorian fires the bullets from his mouth, where the muzzle flashes are obviously CGI. Another example of the Mask's power is that Dorian fires more bullets from his mouth than Niko fired into him.
After Mask/Stanley Ipkiss (Jim Carrey) causes all of the Edge City PD to sing and dance with him, Lt. Mitch Kellaway (Peter Riegert) grabs an Federal L5 Federal Gas Riot Gun and fires it into the air to get the officers' attentions.
