I've had a CMMG Banshee 200 for a couple years now. Shoots any ammo, suprisingly accurate, solidly built, compact size. Wife even doesn't mind it !
Being 9mm it won't go thru to many walls. Recoil spring noise does sound like an early M-16 ! And with a loaded glock 32rd mag . . . . .
Fun and easy to shoot . . . . . problem is WOW you can go thru a box of ammo quickly ! !
