The Big Lebowski

The following firearms were used in the film The Big Lebowski:

The Big Lebowski (1998).

M1911A1

Walter Sobchak (John Goodman) pulls a M1911A1 from his bowling bag and tells a fellow bowler he will be in a "world of pain" if he doesn't mark his score correctly. The gun is probably something he carried over from his service in Vietnam.

M1911A1 - .45 ACP.

Walter pulls the 1911 from his bag.

Walter calmly gives Smokey his "world of pain" speech. Dude (Jeff Bridges) sits at the left, Theodore Donald 'Donny' Kerabatsos (Steve Buscemi) in the center.

Walter aims his 1911 at Smokey.

Walter waits for Smokey to mark his score. It should also be noted that pulling a firearm during league-play is generally not acceptable.

Uzi

Walter carries an Uzi wrapped in brown paper when going to meet the kidnappers. The weapon fires upon being dropped on the ground when he exits the vehicle. It is concealed in the paper bag during the entirety of its screen time, only being identified as an Uzi by Walter.

Heckler & Koch MP5K

One of the German Nihilists (Flea of the Red Hot Chili Peppers) whom the Dude, Walter, and Donny encounter towards the end of the film has a Heckler & Koch MP5K. Walter disarms him with a well-aimed bowling ball.
