Gay Perry (Val Kilmer) carries a NAA .22 Magnum Mini-Revolver, and gives it a pejorative nickname due to the fact that it only fires 5 shots and needs to dropped for something better. It is used from a very unusual place late in the film.

The gun that is planted in Harry's (Robert Downey Jr.) hotel room is a Ruger SP101. Harmony Faith Lane (Michelle Monaghan) uses it by accident in the park and Harry uses it in a mathematically inaccurate game of Russian roulette at the clinic.
What appears to be a Colt Detective Special is used by Harlan Dexter (Corbin Bernsen), who is seen on a television in the role of Johnny Gossamer in a movie adaptation one of the Joe Chester novels. This clip is actually from Dead Aim, a movie that Bernsen previously starred in.
