Want to make my own custom skin

Need help finding the physgun VTF and the sprites, can anyone help? I’m trying to make my own reskin.

Get a program called “GCFScape”. This reads the gcf files that the source engine’s files are packed into. Either gmod has it’s own skin, which you should search for in the “garrysmod content.gcf” file. If there is nothing there try looking in “Source materials.gcf”.
