I fully expect the hi-point to be named on the upcoming ban list just because it looks evil.
wait and see if my crystal ball is wrong.
With that said, I really like handgun caliber carbines. The longer barrel gets more velocity than the shorter pistol length barrels. It's almost equivelant of getting +P velocities from regular over the counter loads, better accuracy at long range (75 or more yards) due to being able to hold it on target better, etc.
There's a lot of reasons to like true to the definition carbines.
