I wanted a gen 5 model to start with so that I could fill in most of the internals and then use the G100 boolean negative to subtract away what I need to make it compatible with the G100 fire control unit. All that its really going to do is make it look like a gen 5 glock externally and also gen 5 mag release. I guess its not that important because I've already found a 19x file that was gen 3 compatible and modified it to accept the g100 chassis. I was just hoping that there was a gen 5 replica model somewhere to start with so I could make one more true to an actual gen 5 frame. I haven't tried printing yet but I modified this model the past couple days. The biggest hiccup was recontouring the back strap because the G100 chassis is really deep in the trigger housing area because it holds the trigger housing and then also has more material under it for a mounting pin. This makes it dangerously thin in the backstrap around where the pin is. So I added about 1mm more material to the backstrap while trying to maintain the same hump and contour.

EDIT: Its not letting me upload the images so I'll try again later.
