Just checking on the legality of the new XDM Compact, 3.8 inch barrel, 9mm, with the sleeve that fits over the 19 round magazine to give it the grip of the full size XDM, 9mm, 3.8 barrel. I am an IDPA S.O. and cannot find anything in the rule book that would make this gun illegal for ESP in IDPA. But it is fairly new on the market and I am not 100% sure about this. Anybody know for sure? Thanks for replies.
