From Dusk Till Dawn (1996)

Seth Gecko's .44 Revolver

The exact model of Seth Gecko's (George Clooney) revolver seems to be of some contention, but the two prominent contenders are Smith & Wesson's Model 29 and the Astra Terminator. I am inclined to believe the latter, although the S&W is a possibility. It's certainly a .44 6-shot revolver with a 3" barrel, with a blued finish and pachmyr grips. It is later picked up and fired by both Scott (Ernest Liu) and Kate Fuller (Juliette Lewis).

"You ask a question, Mr.44 answers it."

Richard Gecko's M1911

Although we could speculate about the manufacturer of the pistol carried by Richard Gecko (Quentin Tarantino), it is undoubtedly a 1911 Government model, possibly nickel plated.

"When I count to three you shoot the bottles out from behind him!"

Unknown .357 Revolver

The liquor store clerk (Pete Bottoms) draws an unknown silver 4" revolver from his safe and shoots Richie (Quentin Tarantino) through the hand with it. By the looks of it it's probably a .357 Magnum, one of various possible makes and models.

Shotguns

Jacob Fuller (Harvey Keitel) locates a pistol gripped 12 Gauge shotgun under the bar and uses it with a baseball bat to make a cross to both repel and shoot vampires. This has been suggested to be a Mossberg 500 and it seems likely.

Additionally, the two shotguns weilded by Danny and Manny seem to be Mossbergs as well.
