I found the gun model on a site were people share their artwork, and the guy who made that said that he had been using original blueprints. You can still see some details that are not quite right, and I might fix these once (if) I get proficient enough with the 3D software.
That line between the grip and the frame is actually there, but it doesn't show in the rendering due to the artificial glare. And really, there isn't much of a transition with a well fitted set of grips so the lack of checkering almost makes it look like the grips just run into the frame without a seam.
Checkering would be nice, and I would also like to fix the "Indian gap" between the grip and the side plate. I suspect that the guy drew the right panel first, and simply mirrored it to make the left panel. The stock lug is there, not 100% correct but fairly nicely done.
The text can be whatever I want it to be, and you can add all kinds of stuff like insignias, flags etc. It's pretty time consuming to make the 3D model, even if you already have the gun itself, but it's a lot of fun as well. I actually made another one and ran it in the CNC last night. I gave it to a friend of mine this morning and forgot to take a picture, but this is what the rendering looks like.
As you can see, the gun is not 100% here either. The spring housing sticks out too far and the safety is in the wrong position, but it's still not bad for a free download
