The Browning Hi Power in the film would most likely have been a 9mm. The movie was released in 1988 and the .40S&W variant of the Hi Power was not marketed until 1992.

Revolvers
Miguel has this. It's seen fleetingly when he forces Sue into Rico's limo, and stuck in the waistband of his pants in other scenes.

The grips are S&W, look stainless, I would go with Model 66. --Predator20 23:02, 23 January 2011 (UTC)

I can't see if it has a vented rib, so either Colt Python or S&W Model 586. --Predator20 23:06, 23 January 2011 (UTC)
