Thanks Slanto, I checked them out 2 days ago, after DrNick wrote about them. I'd go for the Unit 2 myself, for at least $100 cheaper. But the question is: Can we get the Marvel units in Canada? If not, it might be cheaper to just try to adapt a Kimber unit to the Para and modify an original Para mag to fit a Kimber .22LR mag inside of it. That is, if you can find a full body mag, instead of the POS 2/3 body mags Para sells here in Canada.
My quest goes on...
