Found a used one on Gunbroker, so I snagged it for $504 plus shipping. Not bad. The local shop that was going to get me one that takes Cougar mags (I would convert it to use 92 mags) for $549 can't get anymore. I checked other local shops... Sportsman's Warehouse didn't have any at the moment, and their price was $619. McBride's had one, but they want $655 for it. One place called 'Cost Plus 10%' may or may not have actually had one, but they wanted $650.
Geeze, prices must have gone up on these things! I recall someone saying a local shop had the 9mm CX4 for $529 shortly after they came out.
I don't think this one will have any mags, so I'll order a couple 20 round MecGar mags from Midway USA. It doesn't have the case it came in, but it does look like it has one of the side rails on it, which I wanted anyway. I want to get the other side rail, and the top rail. Set up a three point sling on the left side, get a weapon light for the right side, and some manner of dot sight on the top.
I'll post a review/range report once I get it and get some rounds through it!
