Okay, guys.
Before you flame me here, I know that not many people like Special Weapons here and I know why. Living in AZ, I get to talk with them first hand. Not all of them are bad guys.
I have an SW45FS. It's the 45 MP5 clone with a short barrel and tacked on fake suppressor. This this is accurate and if you have good mags, very reliable. It's a fraction of the cost of a real HK. I'm an HK guy. I own 4 real HK's. The only thing that is not really HK on this clone is the rec. Everything else is real HK parts. They even put a plastic lower with the SEF trigger group. Looks just like a real subgun, but fires semi only. I have lots of fun with it.
You can get 9mm models for 1100 to 1400. If you have 4k to spend on a semi HK94, great! I'd rather buy a real M16 with that cash.
My opinion.
