The following weapons were used in the film Blow:
Several Colt M1911A1s are used during the film. A South American drug dealer, Alessandro (Miguel Perez), who Diego Delgado (Jordi Mollà) had a falling out with sticks a black 1911 in George Jung's (Johnny Depp) mouth. When George goes to see Diego on Norman Cay, he holds an unloaded silver 1911 with diamond grips to Diego's head and then his own. In real life, George Jung's favorite weapon of choice was a nickel-plated Smith & Wesson .357 Magnum revolver with walnut grips.
Smith & Wesson 915
During the montage showing George and Mirtha's "romance" leading up to their marriage, George (Johnny Depp) holds a Smith & Wesson 915 on Mirtha. This would be anachronistic as this scene takes place in 1977, several years before the S&W 915 was developed.
Smith & Wesson Model 66
Colt Detective Special
One of the South American drug dealers during George and Diego's argument pulls out a third-generation Colt Detective Special.
Smith & Wesson Model 15
One of the South American drug dealers during George and Diego's argument pulls out what appears to be a Smith & Wesson Model 15 with a 4" barrel.
Smith & Wesson Model 10 Snubnose
One of the South American drug dealers during George and Diego's argument pulls out a Smith & Wesson Model 10 with a two inch barrel.
Smith & Wesson Model 15 Snubnose
The "waiters" (undercover FBI and DEA agents) who arrest George at his 38th birthday party carry Smith & Wesson Model 15 with two-inch barrels.
M3 Grease Gun
Several of the guards at the cocaine manufacturing plant in the opening credits and some of Diego's guards carry M3 Grease Guns.
The Panamanian bank guards carry M16A2 rifles as George and Diego wheel in $30 million. Diego's guards on Norman Cay also hold M16 variants.
- The rifle used by Diego's man has carbine-length hand guards, so it is not an M16A2. Though I can't tell what it is from this picture. -MT2008
The police officers working with the FBI and DEA in Florida use Ithaca 37 shotguns when arresting George for the final time.
