KIFFLOM, brothers.. The original model from the game files, which was never included in the final version of the game, therefore has the original SA style and lies smoothly in the hands. I just did a retexture.
Also, the model has not just a chrome texture, but also a shine, which creates the effect of chrome. Installing it is impossible: armed with the Crazy IMG Editor, add the replacement files from the archive to gta3.img. Or, if you have Modloader... Yes, you know everything yourself.
