I e-mailed MKS about the possible release of the Hi-Point carbine in .45 and they said that it will be released in mid to late 2005. I suggested that they make a heat shield like on some tactical shotguns to make the carbine more streamline. I e-mailed them back to see what kind of capacity we could expect, but have not heard back as of yet. I will definatly pick one of these up when they are released and if they dont release the heat shield I will make on fit.
