The following guns were used in the film Shane:
Single Action Army
Shane (Alan Ladd) uses a 7 1/2" Single Action Army Cavalry with a nickel finish and ivory grips as his sidearm in the film. Jack Wilson (Jack Palance) carries two Colt SAA's, and several characters use them as well. Joe Starrett (Van Heflin) takes out an ivory handled Colt double-action when he's about to go after Ryker. Stonewall says that he will start using his .38, but when we see him use his gun, it's a Colt SAA.
Winchester Model 1873
Ryker's brother is seen walking upstairs to stay hidden and armed with a Winchester Model 1873.
Joey Starrett (Brandon De Wilde) carries a .22 rimfire Stevens Crackshot around to play with, but his father won't give him any rounds for it because he is too young. When Joey works the lever while Shane is there, he whips around, ready to draw his pistol before realizing the situation.
12 Gauge Double Barrel Shotgun
When Joe Starrett (Van Heflin) talks to Morgan Ryker about meeting his brother Rufus he is seen carrying a double barrel shotgun.
Several Flintlock rifles are hung up in the town bar.
