Shot both yesterday - I have a Burke and my buddy has a GG - both excellent. Major difference to me is the Burke is IDPA and USPSA legal by the letter of the law. Shot first match, IDPA Sat, finished 2nd OA, 1st ESP, 1st Senior.
I'll take it considering I had never drawn the gun from a holster 'til the 1st stage. ? Good start for the X5.
