Ok, this is not at all to knock anyone, so please don't take it that way.
I look at all these sub machine guns in semi-auto out there and ask myself: "Why would anyone even want one?
For plinking they seem kinda lame. I can plink with a pistol that has obvious strong points (concealability, etc) or a rifle where I can really push my marksmanship skills.
For tactical use, well, honestly wouldn't a M4 semi work as well or better?
I'd love to have a full auto MP5 or Thompson, but I wouldn't spend anything on a semi-version of these cause I just kinda think to myself Whats the point?
Is anyone else left cold by these things or is it just me?
Bill, I take it you've never had the pleasure of a GSG-5?

Great fun to shoot, and everyone else at the range is in awe until they hear the .22 report that comes out of it.
And Ray, I know nothing about the HK 94, but I did find this:
