Aside from just being fun to shoot, what's the consensus on the real usefulness of a pistol caliber carbine?
From what I understand most agencies are starting to adopt SBR intermediate cartridge carbines to fill the role that a good pistol cal carbine filled. I can see how something as compact as an MP5 or UMP45 might be good in a home defense or house clearing type scenario but an SBR AR15 could do the same thing with more power. Over penetration might become an issue but there are supposedly tailor made cartridges that are designed not to pass through walls.
I ask because I am thinking about ditching my pistol cal carbine in favor of a cheaper SBR in either 300 BO or 7.62x39 fro a general purpose HD/Truck gun.
Thoughts?
