I bought mine because I wanted a defensive rifle I could use if injured. Also, because the performance of the round is better in a pistol than alternatives. It's a handy package. The 4pc brake is practically a necessity to manage the muzzle blast. The arm brace works if you blade off to the target. Isosceles is a no go unless you hold it gangsta with a reflex. I did a thread on getting mine to work in the gunsmithing section.
Also, wear both plugs and muffs when you fire it.
