Well, sign me up for a window seat on the short bus I guess.

I have a 4" 9mm AR PCC/SBR. It keeps standard 147g subsonic, some lighter rounds as well.. The can is buried in the rail. My goal was a stocked, suppressed "Glock 19" carbine with a light and a red dot. The intended mission is interior home defense and being able to hear the cops well enough to know when to ask for a lawyer afterwards.
