Ben this is actually an older one. I don't think they make the V10 ported ones anymore. It's tough up here, used colt are going 700 and up, new smiths with anything but fixed sites, are like 900 +, the scandiums are like 900.... This crap sucks..
No need for a ported, but the gun has to be Mass Compliant. Para's new ones are not compliant yet, they were supposed to get it done, don't know what is taking them so long. I think I am going to wait I heard good stuff about the new line of Para's, and I got a 14-45 limited that I love.
