I decided to take a series of locally held defensive handgun courses over the next few months. My C9 is relatively new...(I've had a Hipoint carbine for some time)...and I've only taken it to the range once to date. It's not my EDC, which is a Colt .380, but I'd like to use a 9mm on the course. Incidentally, I called first: The instructor was not a gun snob and, although he's not used a Hipoint himself, he was genuinely interested in seeing it in action during the training. One of the recommendations for the course was a plastic or Kydex single or double magazine holder. (I'd prefer the double myself, for the 10 round magazine). I've searched the forum but couldn't find any recent info on any particular models that could be confirmed to work well with the C9 magazines, so I figured I'd ask here first. As always, any recommendations would be appreciated.
