Lethal Weapon 4

The following guns were used in the movie Lethal Weapon 4

Lethal Weapon 4 (1998)

Beretta M92FS

As in all the previous Lethal Weapon films, Detective Martin Riggs (Mel Gibson) carries a Beretta M92FS as his weapon of choice, albeit this time fitted with a laser pointer integrated into the guide rod. At one point in the film, the pistol is rendered unusable when the lead villain, Wah Sing Ku (Jet Li), manages to take the gun apart by separating the slide and barrel from the frame although he seems to have repaired it after words because he is seen weilding it in the final shootout and at the end.

Beretta 92FS - 9mm. This well worn movie gun is the Beretta 92FS that Mel Gibson used in Lethal Weapon 2, Lethal Weapon 3 and Lethal Weapon 4.

Detective Riggs aims his Beretta M92FS at Wah Sing Ku's (Jet Li) head. Wah Sing Ku is carrying a Makarov. Note that in this photo, the takedown lever on the frame of the Beretta is rotated downward at a 90-degree angle; this is how Jet Li was able to separate the slide and barrel from the frame so quickly.

Smith & Wesson Model 19

As in all the previous Lethal Weapon films, Detective Roger Murtaugh (Danny Glover) carries a Smith & Wesson Model 19 revolver as his standard weapon.

Smith & Wesson 5906

As in the previous Lethal Weapon film, Detective Murtaugh uses a Smith & Wesson 5906 as his back-up weapon. Detective Riggs also brandishes this weapon during the encounter at Murtaugh's house.

At the beginning of the film, Riggs and Murtaugh respond to a call of a man dressed in a fireproof suit wreaking havoc with a flame thrower, torching anything that comes near.

Makarov PM

Several members of the Chinese triad can be seen wielding Makarov PM pistols, most notably during the encounter in Murtaugh's house. From closer examination of the pistols, it appears that the Makarovs used by the triads were Chinese-made Norinco copies of the Makarov PM.

Type 56-1

Near the end of the film, a three-way gun battle erupts between the protagonists, Chinese triad members, and the private army of a corrupt Chinese General. The General's men can be seen wielding Type 56 and Type 56-1's, one of which Riggs gets ahold of to kill Wah Sing Ku (Jet Li), firing the weapon point-blank while both of them are underwater.

Note: Not an AK-47 as originally thought, not with the folding stock, and considering the fact that the sight was most likely hooded, it must be a Type 56-1.

I don't think it's a Type 56. The Type 56-2 (which is the version with the side-folding stock) has a different stock design than that. The Type 56 also retains the smooth receiver cover of the older AK-47 models (as opposed to the strengthened ribbed design of the AKM), but that rifle looks like it might have a ribbed one. East German MPiKMs do have stocks that look like that and ribbed receiver covers, so I'm guessing it might be one of those. I would need to see the front sight, as well as the receiver, in better detail to figure out whether it's a Type 56.

It's either an East German or Romanian side folding stock. It has to be an AKM, not a Type 56, because the side folding stocks don't fit on the Chinese receivers. MoviePropMaster2008

Micro Uzi?

If i remember correctly, IMI did have a semi-automatic variant of the Micro Uzi advertised as the Uzi Pistols. I can't immediately remember all the differences, aside from a slightly different grip and the obvious semi-automatic-only firing capability.
