I would say that you got the better part of the deal, even for a mixmaster. I can see where your grandson would have liked it (compact, easy on small hands, etc), but the carbine is definitely the cooler of the two toys.

I was curious about a couple of things on your grandson's new toy.... The trigger housing has the oil hole drilled but it looks like a Q-NL marked type II or III (can't see the rear lugs). Also, it looks like a type II slide but that looks like a hand-eched N 9 in the bottom?? (I really need to either get coffee or learn how to focus this computer screen in the morning). Got any more pics of those areas?

Oh, and haven't I already given you the lecture about how terrible it is of you to get your grandson addicted to collecting and shooting firearms???? Typical grandfather... Spoil them then send them home !!
