I owned two MicroMags, pics of which were on my old computer.
One was a fixed barrel powerfeed in a matte gray finish.
The other was a gold dust vertical feed body.
I loved the way they both looked, but could never get either to work right. The velocity on the fixed barrel wouldn't go above 230 even with air venting out the back of the valve, and the gold one would never reset the trigger. I tried swapping valves, but to no avail.
