Is this normal? This is a brand new gun and when the trigger is pulled and the sear is engaged , the frame above the trigger on the right side, bulges out slightly. Enough to feel and see. I have never noticed this with my other poly guns in Glock, XD, Taurus, Ruger, Etc. well, i did have an old Taurus Millennium 9mm that did this. But other than that, no other gun. Should i be concerned?
