I present to your attention my first model of a weapon - Glock 22. Probably, this is the most popular choice among beginners) I won't say that it was ultra difficult for me, but it caused me a couple of difficulties. For example, the high poly version... it was something) Since I made high poly for subdivision, and the geometry is quite complex, I, of course, had a hard time with the mesh, but then I found out that most people make complex high poly models in zbrush (literally in a couple of clicks) for me it was an American discovery... well, now I know).
