Neat 18DAI! I may be a little biased in favor of those CQBs though. I bought the alloy 4563 CQB back around '98 IIRC. I was so impressed I went in search of the all stainless like yours. I was able to find a new 4566 CQB back around '99 or 2000 I think it was. Had it till a couple years ago, don't think I ever put even a hundred rounds through it. I did carry the alloy 4563 CQB for about a year and a half though, and it shows it. Never got into any shoot outs or anything with the alloy CQB, but through all kinds of training and qualifications, never a malfunction of any kind. The CQBs are confidence inspiring guns IMHO. By the way, spoke to Vito on the phone a couple of times. He did some revolver work for me. I hope he enjoys the whole retirement thing as much as I do
