Have a set of Shadow 2 aluminum LOK short grips and magwell on order, want to ask for those that tried it, if my current Taran Tactical CZ +4 basepads on MecGar 17rnd mags fits the magwell? Or do I have to modify the magwell? Or buy some other basepads? Asking, because the TTI has a protruding pin at the back , that looks like it will hit the back of the magwell. Thanks.
