I didn't like the aggressive grip either. Almost painful on mine and I don't have soft hands. First desert shoot and I pulled out my pocket knife and with swiping motion removed the tips front, rear, and sides. Helped greatly! Gave it a mildly aggressive feel. Did a stipple job on it a month later. F'n fantastic now!
Mag release is difficult, bordering on impossible, to actuate one handed, but I haven't polished it yet.
