I've got on order a Glock 23 .40 cal. Gen 3 and a Crimson Trace Lightguard Flashlight. I've been reading that the 22 and 23 .40 cal. have had some issues with tac lights. Since the CT lights mount differently I was hoping there would be no issues. Does anybody have any knowledge or experinece with this? FYI this is my first Glock and my first post, joined this forum yesterday.
