I just placed my order an hour ago and will be posting a report ASAP. In the meantime I will give the Kimber Tactical Pro magazine a rating of A. The Kimber may deserve higher but I'm not yet certain as Wilson Combat is the standard by which others are judged but suffice it to say that the Kimber Pro Tac has been flawless through several hundred rounds. The finish is very good, slide lock worked everytime, ejection of the magazine was no problem. There have been no feed issues. In my opinion this Kimber Pro Tac is one of the best magazines I have tried but still needs to be compared to the Gold Standard which is on it's way. Stay Tuned.
