M&P 9/40 (Compact) Magazine Extension V2

about

Here is an updated file for my M&P 9/40c Magazine Extension. It is overall thicker and stronger. I used the same M2 x 5mm allen head bolt to secure the extension. 

I print these flattest side down (backside) with Tri-Hex infill @ 100% for best results.
