hold 9mm , micro smg , tec9 and sawed off like gangsters

[mememaster25]

hey guys so i was wondering if theres a mod or something to make cj hold the gun like a one of the gangsters and when he walks backwars to hold the left hand up like the other peds  if u know what i mean (sorry for my bad english xd). ive seen an old topic similar to this but people couldnt figure out what to do so if someone could tell me how to do this it would be great . btw i tried to mess up in the weapon.dat file but no results the only thing that kinda worked it was that cj was holding the pistol up to the sky and the left hand up but didnt worked for the smgs and sawed off. if someone could make the mod i will give him a cookie. btw i have another idea like theres a walkstyle mod  why not a shooting style mod
