I’m going to just see if my local gunsmith will look at it. I filed for a warranty claim a week ago, and called them Monday. I still haven’t even received a RMA # to send it back. Pretty horrible customer service IMO. If I can’t get the local smith to look at it for a reasonable price I’ll just return it to Palmetto and cut my losses. Pretty bummed out because I love my Shadow 2’s and DWX.
My understanding is that Colt is taking over CZ-USA's warranty work, so may be an issue in that transition...
Regarding the "deal" you got -- CZ's new MSRP is making it's way into retail channels now as older, more expensive inventory is cleared out, so $399 should be about standard real world pricing moving forward.
