I have the Alien Gear 3.5 Cloak Tuck IWB for my EMP4 CCC and I love it. I am thinking about getting their Shapeshifter 1911 5 inch for it as well. I think it will just have an inch of extra space at the end of the barrel but will otherwise fit well.
I love my Alien Gear Cloak Tuck 3.5. I carry in the 4:00 O’Clock position and find it to be very comfortable with my EMP4 CCC. Their 30 day test drive is nice.
