Mr. White (Harvey Keitel), Mr. Orange (Tim Roth), Mr. Pink (Steve Buscemi), and Mr. Blonde (Michael Madsen) were all armed with one Smith & Wesson Model 659 9mm pistol. They are distinguished from 1911s and other Smith & Wesson variants by their second generation features, stainless steel construction, and double stack frames. Though all of the guns look to be the same, some have the old squared trigger guards, and some have round ones.
Though everyone is given a Smith & Wesson Model 659 for the robbery, Mr. White (Harvey Keitel) is seen using a Smith & Wesson Model 639 with Pachmayr grips. We can assume, being that he is a professional thief, that this is his personal gun, and not a continuity error in the film. During the getaway, he is seen dual wielding his personal Smith & Wesson Model 639 with his issued Smith & Wesson Model 659, further strengthening this theory. In the special edition DVD, on the second disk a deleted scene can be found which briefly shows Mr White's/Larry Dimmick's police record. This informs us that his weapon of choice is a Smith and Wesson 9mm, even further strengthening the personal 639 theory.
Mr.Orange, packs 2 handguns while getting ready to meet Eddie and Mr. White for a meeting with Joe. The automatic he holsters on his ankle is a Beretta Jetfire in .25 ACP.
Mr. Orange's second gun is a Charter Arms Off Duty with Pachmayr grips. He checks to make sure the cylinder is loaded, swings the cylinder back in, and then places it in his coat pocket.
After Mr. White (Harvey Keitel) kills the pursuing cops with his two pistols, he and Mr. Orange (Tim Roth) walk until they find a car driving by. They aim their guns at the driver, a woman, and attempt to take it. She produces a pre-1972 nickel plated Colt Detective Special from her glove compartment and shoots Mr. Orange in the stomach as he opens the door to pull her out of the car. Another Detective Special is "Mexican carried" by Joe (Lawrence Tierney), distinguished as a Detective Special by it's round edged butt.
