I will post pictures as soon as I figure it out???? But I am using STI mag bodies, Dawson base pads, and Grams internals. The mags lock into the pistol positively, loaded or not loaded. There is rattle, but no more than with the RIA magwell. There is ever so slight contact with the base pad and rear of the magwell, but doesn't hinder the mag locking in the pistol. The magwell also does not restrict or bind while insertion or extraction. It is raining, so if it stops today or tomorrow, I will post results after shooting.
