I'm sure it's a fun range toy and an interesting conversation piece, but...
Ask yourself why pistol configuration rifles (Dracos, AR pistols, etc.) are not used by any serious CQB force to fight inside of structures?
Is it lethal? Yes. Could you use it? Yes. But why would you want to? It's a niche weapon best suited to firing from a cramped car interior at someone standing a few feet away. Like a pistol grip only shotgun, the configuration is a huge compromise designed for unique circumstances.
You could mitigate some of the design shortcomings through judicious load selection and a lot of practice, but (IMHO), the juice isn't worth the squeeze. I'm not talking about accurately busting some caps at paper (which can be accomplished quite handily), but rather, fighting for your life against an armed and moving opponent.
The weapon delivers poor ergonomics for fighting, reduced muzzle velocity & bullet lethality, terrific muzzle blast & fireball, a terribly designed combat rifle safety, poor ability to deliver controllable followup shots, and mediocre practical accuracy.
Other than that, Mrs. Lincoln enjoyed the show.
