We bought a Hi-Point carbine and love it! For our carry we use .380 auto pistols and we bought the .380 caliber carbine so we could use the same ammo. With a red/green dot on it both of us can hit a target center mass quite nicely at a distance.

Here is Muhaden, my bodyguard, with my vehicle, on our way in Iraq in the Baghdad area, back from the airport to the Green Zone for the night. I believe he was using a H&K MP-5. He was a local from Baghdad, seemed like a nice guy!
