Just something I worked on for the last 4 or 5 days, to take a break from programming. It's the first time I don't get any shading errors, the first time I get a pistol grip/handle kind of right, and many other firsts. As always, it's my best result up to this day. Lol.
Game-ready asset. 5.1k tris with magazine. One material with 2K maps for the whole thing. Available for purchase at a very reasonable price on the Unity Asset Store: https://assetstore.unity.com/packages/3d/props/weapons/fps-weapon-pistol-175133#description
I didn't render a wireframe, but feel free to leave the feedback you can gather from the render in the comments. Have a great day!
