I am fairly certain that EAA is currently as helpful as they were with the K2 45 a few years ago(which isn't much since sarcasm can be difficult to convey at times). The EAA serial number doohickey thing on their website keeps showing error messages while I am looking up which magazines to buy for my Polymer Compact. I have sent them 2 emails over the last 2 weeks with no response.
I guess I will just have to wait for the Witness full size polymer that I picked up on gunbroker to see for myself.
