The shotgun seen in this movie is a Browning Double Automatic, strange choice as this gun only held two shots at once, though it is very easy to keep loaded via the loading port on the side. O'Niel (Sean Connery), Sheppard (Peter Boyle), and the other police all use them. The two hitmen hired to kill O'Niel use them as well, with infrared scopes attached. Interesting to note is that one of the hitmen is (P.H. Moriarty) who played Hatchet Harry in Lock, Stock and Two Smoking Barrels.

Note that this small loading port is on the other side of the shotgun than the ejection port. These shotguns only hold two shells, the first shell loaded goes directly into the chamber, and the second loads automatically after firing the first.Error creating thumbnail: File missingO'Neil pulls back the action....Error creating thumbnail: File missing....and let's it go, locked and loaded. This is the standard side for the ejector port (for right handed shooters).Error creating thumbnail: File missingO'Neil returns fire on a hitman with his Browning Double Automatic. This scene is a little confusing, as both him and the hitman fire more than 2 shots at once, though they don't appear to fire more than twice between cuts.
