M1911 I made in about 3 days. 6.3K tris. One material with 2K PBR maps. Game-ready (duh).
This one was really fun to make, I definitely recommend it to beginner weapon artists. Don't really know how I feel about the textures. It's available for free on Sketchfab and I'll also upload it to the Unity Asset Store.
Feedback is welcome but keep in mind I made this in three days (school is coming). Cheers.
