I just picked up one of these magazine holders for the P3-AT . It's a handy way to carry an extra mag.

With a little patience, some cardboard for mock up, a heat gun and some 1/8" ABS you can make similar yourself.
I recently made a horizontal and a vertical single magazine pouch. I'll admit it took me two tries on each one until I got them just like I wanted...and I burned my fingers, but, I'm retired...
