I can’t figure out how to connect the trigger guard with the top of the gun please help pictures below. I’d rather not just extrude right through the mesh either. I decided to start out with a plane then modeled from there, it appears to be an easier start for me.
I don’t think you need to connect those edge.
for this kind of model that doesn’t need smooth transition between 2 parts,
pushing the end vertices inside the body just a bit would be fine.
if you really need to connect them, find tutorial on redirecting edge loop or something like this.
basically, refine the mesh for edge count to match, but you will get more unnecessary faces in return.
