I was hoping to find a carbine in .40 or .45. The few I found are one by HiPoint and the Kel-Tec SUB2000, and the CX4 Storm. The Kel-Tec would suit my purpose for it more because of the acceptance of my SIG .40 mags, but my experience with kel-tec hasn't been that great. Has anyone tried either of the two and/or have opinions on other carbines that shoot .40 or .45? I haven't been able to find a .45 yet
