Here's my solution for the bullets. Take a piece of thin clear plastic and cut it to fit exactly inside the magazine. Then place on to graph paper to ensure horizontal alignment of the bullets. Epoxy the bullets on to the plastic at the rear so it will not be seen when inside the mag. When dry, slip the bullets in to mag and voila!
I actually made the plastic long enough to take the bullets right up in to the slide, but there is an internal piece of casting behind the trigger which prevents anything going higher than the top of the mag. Still looks great.
