True to his real life counterpart, Gen. George S. Patton (George C. Scott) in the film carries an ivory-gripped Single Action Army in his holster with his initials "GSP" engraved on the grip. When a reporter asks him about his "pearl-handled revolvers", Patton quickly retorts "They're ivory. Only a pimp from a cheap New Orleans whorehouse would carry a pearl-handled pistol."
-Fact: Patton (and his real life conterpart) only carry one ivory handle Colt 1873 Single Action Army. The second pistol he carried was an ivory handle Smith and Wesson .357 magnum, later given the designation Model 27. The Single Action Army was engraved and had an Eagle carved into the left grip panel. Both the Model 27 and Single Action Army also had Patton's monogram on the right grip panel. The SAA can be seen in this link: [1]
Smith & Wesson Model 27
Patton's signature ivory-handled SAA is replaced by a Smith & Wesson Model 27 with his "GSP" initials engraved on it for the shot during his opening speech. General Patton purchased the Smith & Wesson Model 27 in 1935 directly from Smith & Wesson. He had the nickname "Two Guns" as he wore matching Colt SSA that he had until giving one away as a gift. He then wore that Smith & Wesson in place of the one given away. He also wore Colt 1908 Hammerless Pistol and a Remington Model 51 pistol.
The Smith & Wesson Patton carried wasn't yet called the Model 27. They were known as Registered Magnums, the first of the 357s and special order. I'm not sure about the one in the movie, but notice the hammer difference in the movie picture. Patton I believe called his Registered Magnum his "killing gun."
Some of the Morrocan troops that line up for Patton carry MAT-49 submachine guns. These are anachronistic for the scene, which takes place in 1943, as they weren't developed until a few years later.

Browning M2 Aircraft
Patton himself holds onto the barrel of a Browning M2 Aircraft while riding atop a half-track on his way to his new headquarters in North Africa.
Colt Model 1903 Hammerless
Patton also carries a Colt Model 1903 Hammerless as a personal sidearm (kept either in his waistband or a shoulder holster), most notably using it to shoot at a German plane that fires at his headquarters in North Africa. Major General Walter Bedell Smith (Ed Binns) also carries a Colt Model '03 in a shoulder holster.
I don't think this is the M1. If you closely this one lacks the foregrip of the M1 and, in addition, it seems to have a larger diameter. This could be either the M9A1 (2.36 inch) or the M20 "Super Bazooka" (3.5 inch).Charon68
