What enefgee said, plus it is an absolute hoot to shoot. I blasted away with one with a full capacity magazine in Minnesota. It is a shame they can't hold 50 here.
Really cool looking, shame its only 5rd capacity, and a funny caliber. I would be scared about finding food to feed it and the cost of it
Im dying to buy some kind of 9mm or .40 SMG style gun. I love my KRISS vector and would love something similar in a 9mm with 10rd capacity. If this was a 9mm Id be really interested in one
The Gen 2 Vector is available in 9mm. Also IRG has some 9mm AR's pretty well priced.
I know someone who is working on converting a PS90 to a .17 super mag.
I would happily own one, but never will. I liked what I saw when I played with one. However it is at the bottom of my buy list. Its not practical for much in Canada. But it would be a fun range toy if you have lots if cash to waste wich I don't.
I was out shooting mine literally today (with my fresh Harron barrel). I can say it is even better then it was before with the bit of extra length. The ps90 is a joy to shoot and I can say nothing bad about it. Bottom line is simple, if you are buying exotic euro rifles you have to deal with the issues of keeping one. Gun cost and ammo in this case is a big one, but it is a very unique experience just like the FiveseveN.
Regarding your original question though, I would think the 10 inch barrel would greatly reduce the accuracy, but would look way cooler.
