Murderers' Row is a 1966 spy comedy directed by Henry Levin. It's the second of four films about the adventures of "super spy" Matt Helm (portrayed by Dean Martin), preceded by The Silencers (1966) and followed by The Ambushers (1967) and The Wrecking Crew (1969).
The plot of the film revolves around the attempt of Bureau of International Government and Order ("BIG O"), usual "bad guys" of Matt Helm series, to create a heliobeam weapon of mass destruction. So they kidnapped Dr. Solaris whom Mutt Helm must find before BIG O will use the weapon to destroy Washington, D.C.
The following weapons were used in the film Murderers' Row:
Matt Helm's (Dean Martin) main weapon and a valuable plot item is a "ten-second delay gun" that appears to be a Hy Hunter Bolomauser, a pistol version of Armalite AR-7 that was manufactured in the 1960s. The pistol several times passes from Matt to other characters and back again.
An BA Gyrojet Short Barrelled Mark 1 Model B pistol is used by Julian Wall (Karl Malden) in one scene. It is fitted with a spear that appears to be taken from the related Gyrojet Lancejet underwater pistol. Despite working on a similar principle, it is not possible to fire these darts from a normal Gyrojet due to the fact that the hammer needs to be able to strike the front of the round to push it back against a fixed firing pin, a physical impossibility with a dart that protrudes through the full length of the firing chamber and barrel.

Note the length of the barrel and position of the front sight which differentiates it from the standard variant, as well as the slightly shorter and more common snub nosed variant. Also, it can be seen that the hammer (the lever located on the left side of the frame directly above the trigger) is not cocked meaning that the gun is incapable of firing.Error creating thumbnail: File missingWall reloads his gun.Error creating thumbnail: File missingThe muzzle can be seen.
"Freezer Pistol"
In one scene Coco Duquette (Camilla Sparv) is seen with a "Freezer Pistol" that produces a spray, capable of turning a man into a snowman. Later this pistol is used by Matt Helm (Dean Martin). The gun resembles a Baby Browning though it could be simply a water pistol.
The guards in Wall's headquarters carry M1 Carbines, fitted with heat shields, pistol grips, underfolding stocks and M9 flash hiders. In one scene Matt Helm (Dean Martin) fires a captured carbine that produces the sound of full-auto fire (like M2 Carbine) but the holes from the bullets appear with the speed of semi-auto shooting.
A six- (or seven?) barreled pistol is used by Julian Wall (Karl Malden) during the chase on hovercrafts. Though various sources claim it to be a Pepperbox version of Gyroject, it's most likely a non-functional movie prop (see Discussion page for detailed arguments).
In one scene Julian Wall's (Karl Malden) is seen. It contains six bolt action rifles with sniper scopes (supposedly Winchester 70s), two M1 Carbines with folding stocks, three revolvers (unidentified), a pistol (bears resemblance with Remington Model 51 but the grip looks more slim), Webley No. 1 Mark 1 flare gun and MBA Gyrojet pistol. Except Gyrojet, other guns aren't used in action.
