Actually read a review in one of the handgun magazines a while back. Seems like it's getting quite a following out west with people who enjoy handgun hunting for small game. The cartridge itself seems like it could be a viable self defense round in capable hands. I forget the down range energy, but it's quite a bit. I think the concept is deffinately there, but the following may be much higher if it was the 22 hornady or 22 colt or some other brand other than coming out in only a ria. There's still some snobs out there who won't own or shoot a ria 1911.
If/when dies are available, it will be nice using the same bullets for your 223 and your 1911...just different cases. From what I have seen on YouTube the round hits pretty hard with a 40 grain bullet.
