Uncharted: Drake's Fortune

The guns used in this PS3 game weren't all fully named, or shorten. Perhaps for copyrights

Makarov PM

The starting handgun of the game for Drake. The game called it the PM 9mm. It has 8 shots, and from what it appears, it looks like the 1971 standard military model.

Beretta 92FS

In the game, it was named the 92FS 9mm with 15 round magazines.

Smith & Wesson Model 29 Revolver

The game called it the Wess 44. So from the number alone, it's a .44 caliber revolver.

Desert Eagle

In the game, they renamed it the Desert 5. 7 round capacity apparently and one of the main villians has a golden one.

Micro Uzi

In the game, it is called the Micro 9mm.

MP-40

MP-40 SMGs that Germans left behind from WWII.

Mossberg 12 gauge shotgun

Unknown model, but in the game it is named Moss 12. Appears to be a Compact Cruiser.

Spas 12

In the game it's named the SAS 12

Dragunov SVD

In the game it is renamed Dragon Sniper rifle

M79 Grenade Launcher

That is what the game named them as. Seems to be M79 grenade launchers fitted with a pistol grip almost is if it were a shotgun, probably for better maneuverability in the jungle, but would reduce accuracy and give it some major recoil.
