March or Die

Pale Rider

Open Range

Have been known to clean a gun or two and then nap to a Saturday or Sunday afternoon ball game.

Personally, I like the Eastwood spaghetti westerns.

Any John Wayne or Bond movie

Iron giant, to infinity and beyond,
The straight story,
The blind side

Casablanca- the best movie ever made.
The Quiet Man- to me, John Wayne's best movie

To Have and Have Not
Rio Bravo
The Petrified Forest

The Untouchables

Jack Reacher
The Outlaw Jodi Wales

It's not a gun movie, really, but I think it pretty neatly checks all the requisite boxes and nobody has mentioned it yet: The Big Lebowski

I've seen it so many times, I can just about go line-for-line through the whole thing. It still cracks me up. It's not really a gun movie unless you count a few scenes with Walter, but it amuses while you work. Trade gun cleaning for knife sharpening and this was what I was up to a few nights ago.

If it's gotta be a gun movie, here's another one I haven't seen mentioned in this thread, and this one speaks for itself: The Boondock Saints. Add in The Matrix as well.

Any Die Hard
Blackhawk Down
Invasion USA
Act of Valor
Either Sicario
Full Metal Jacket
Red Dawn, the first one

The Ghost and the Darkness

Man on Fire
