Lamarr Simms (Don Stroud) carries a C96 "Broomhandle" Mauser as his weapon of choice in the film, and fits the unique holster/stock combo to the back of the grip to shoulder the pistol like a rifle. Joe Kidd (Clint Eastwood) later uses it when escaping from the bounty hunters, and shows us that in Hollywood a ten shot pistol can fire about 30 rounds and lock empty several times before actually needing to be reloaded.
As Joe Kidd (Clint Eastwood) escapes from the bounty hunters, he grabs a rifle case containing a custom built Ross Model 1910 straight pull bolt action rifle that has been sporterized and modified as a break down rifle, and fitted with a Winchester A5 scope. The gun also has a fixed five round magazine instead of the extended ten round version. Joe uses it when battling Olin Mingo (James Wainwright) in a sniper standoff.
Olin Mingo (James Wainwright) carries a Remington-Keene Frontier rifle fitted with a scope and with a shortened magazine tube as his sniper rifle in the film, noted by its external hammer mounted on the back of the bolt. Based on the muzzle diameter it appears to be chambered in .45-70. A similair rifle is seen used in The Sons of Katie Elder.
As with most westerns, many characters carry Single Action Army revolvers in the film, including Joe Kidd (Clint Eastwood), who carries a 7 1/2" Cavalary model. Some characters carry Single Action Armies but never draw them, such as Frank Harlan (Robert Duvall), who has one with ivory grips.
At the beginning of the film when Luis Chama (John Saxon) breaks his friends out of jail, Deputy Sheriff Calvin (Clint Ritchie) is seen using a Colt Bisley Single Action Army noted by its distinct grip shape, and fitted with pearl grips.
Frank Harlan (Robert Duvall) uses a Savage 99 with custom engraving as his rifle in the film. In some scenes, Roy Gannon (Paul Koslo) is seen holding it.
