Glock 17/34 (gen 1-3) +4 mag extension

I designed an extended mag for my Glock 34/ Plasticatto build. This is a large magazine extension for better grip on the mag due to the magwell. I initially designed for a +2 as I know the mag spring can handle it. This is the +4 version. I cannot guarantee it works with factory mag springs, but was tested and fits 21 rnds, just not sure on cycling.

 

I used pained fuzzy on the sides of the mag for grip, but have included an stl with blank panels if you would like to create your own texture.
