Personally, if it's reliable in a tight situation, I would rather carry that around than a standard model. I grant you it would take a little getting used to but it would certainly be handy in tight quarters and if the barrel is full length you wouldn't lose any useful range. Good, innovative design, reliable and proven base weapon, what more could you ask for? I'm not a fan of extended mags so a shorter mag would be even better. By the way I don't like extended mags for personal reasons, I could care less if anyone else wants to use them.
