Man, I wanna some weapons for San Andreas. Let's see if you can do'em:
-Glock 17 (for standard pistol).
-Silver Colt 1911 .45 (same model with silencer).
-Ithaca Model 37 (with woody textures).
-Silver Franchi SPAS-12 (with saved armstock).
-IMI UZI (Micro version for Micro SMG, and normal version for SMG).
-Colt Model 733 (same design than M4A1 but with shorter barrel and the shrunken armstock).
-Winchester Marlin 336W (with woody textures).
-H&K PSG-1 Sniper Rifle (like the SA sniper icon and beta model).
-RPG-7 (with woody textures) with a missile model apart.
-SA-7 Grail (or 9K32 Strela-2).
-Silver M134 Minigun.
These ones for the moment. Do you know why specially this guns? Cuz these are the right models names from the game (and same colors and textures). I recommend make the cutscenes counterparts, keep the original icons, make a better gunflash texture, sniper crosshair, etc.
And you'll see how may people download and enjoy your work
