A while ago I started making 3D weapons on a free modelling program made by google (Google Sketchup)
I haven't really made any for a while but here are a few that I've made.
This is my personal favorite, the 1911

This is an AK47. One of my more recent models. There is an older, crappier version of the ak47 that I might put in here if you guys like.
Here's the 1911 again but not in a showy picture. This is just the overview of the weapon. It's an older version than the one picture above but it's still nice.
If you want to see more, just say so and I'll try to get up some others. Excuse the crappy edges in the pictures, they were made before I discovered the feather selection tool. Also, these aren't the most accurate models because they were made using 1 flat reference image. Enjoy and if you'd like rate each out of 10 :D
