Big thanks to 3DCentralVA for the original model. I read in the comments that the tolerances were very tight and took a lot of sanding which I'm not too fond of doing. So, I started out remixing the cutouts in the body to be a little bigger, then got carried away and designed some new parts too. I usually use a .2 tolerance, so holes need to be .4 over and things that go in holes need to be .4 under for an exact fit. So, I enlarged the cutouts in the body and the holes in the barrel parts .8-1.0mm. The body cutouts came out great but the barrel parts were a little too loose, so I created an slightly bigger barrel. The left and right grips in the original don't seem to match, with one seeming to be a stretched out version of the other which messes with the corner radius so made new ones of those. Then, when I check some screen caps I saw that the "sight" was square, and that the other top component had tubes on both sides that were more rounded, so made new ones of those, and cutouts to the body to match. I got a little carried away with the sight and imagined it being like a "green dot" scope haha. The sight base is separate so it wouldn't need support and give the option of using a different color. I also separated the back from the body to save a little height and give the option of using a different color. Once I printed the body, I noticed one side had some kind of "faceting" (see last pic) on the left side that is actually in the original just hard to see in the preview, so I split my remixed body in half and mirrored the good side and merged them back together. Thank that covers it! Oh and I used Tinkercad.
Here are parts that are were not remixed that you can get from the original design:
