Oh, and your earlier recommendation of an MP5, man I wish I could afford one! I've been stamp collecting lately, mostly suppressors. Up to six now.
Robinson Arms used to make an HK UMP style sub. I can't even find one on the web. Man! What a blaster! My point is that finding something like an MP5 is .45, that's one heck of a gun.
MP5's, in my view, and I may have already said this, are too light. It is so sturdy and fits so well when you present it and at 9mm, you hardly feel like you're shooting a real gun. The RoArms UMP I got to fire was, to me, a perfect balance of that sub style and the feed back and awareness of firing a real deal gun.
I dunno. Hard to explain. That 9 size just, I dunno, it's too easy to get carried away with because of that light feel. And that means foreclosure, cash in retirement, loss of friends, alienation from society in general trying to feed the damn thing....
