Haven't seen these yet.
What are you looking for in a home carbine? 9mm penetrates more than you think. It a little counterintuitive but small and light self defense rilfe rounds (223) have less penetration then 9mm. They loose most of their energy quickly and cause greater damage to soft tissue. where as the 9 doesn't. A hollow point 9mm will often clog with drywall and act as a fmj.
