I've gotten a couple complaints that my tutorials don't actually teach you how to DRAW guns.
I don't know what else to explain so I'll just break down every type of gun I've explained into simple shapes and color coding.
There is no one way to draw guns, and they come in many many different shapes and sizes. This is only the basics.
If you want to learn about every gun, I suggest using google images to reference and/or looking at this site: [link]
Remember, references are your friend. REFERENCE.
