(In The Line of Fire) - Composite Pistol

From In The Line of Fire.

We see John Malkovich's character constructing this two shot, reloadable handgun in the movie. The weapon is used to great effect blowing a toy boat out of the water and killing the two duck hunters mid-way through the flick. Though seen only briefly the weapon appears to take .38 Special rounds.

Not the actual pistol used in the film but a very close copy
