Good idea,,,bad exicution - ERGO TDX-0 Flat Top Tactical Deluxe Zero Angle Precision Grips

First off, I am a huge fan of Ergo grips, so when I saw they had a Zero angle I jumped on one for my AR pistol build. Thats where the excitement ended. The grip IS vertical and has that great Ergo grip feel, but the angle and lack of typical curve creates an almost 90-degree angle where your middle finger will be jammed up and wedged into the trigger guard. I have it installed on an aero M4E1 lower to give you an idea of the trigger guard shape. This might not be an issue on some lowers, but I'd bet it is on most. This issue makes gripping the weapon an awkward and somewhat painful chore and definitely doesn't feel ERGOnomic.
