I just learned of Eric's recent health scare. My best wishes to Eric and his family for a speedy recovery. Drew, I can tell you that my only experience w/ lasers on Glocks was the original CT laser grip that wrapped around the grip. Didn't like it at all, sold it almost immediately. Really, the only things I do to my Glocks are replace the sights (Warrens or Heinies) and stretch a piece of bicycle innertube over the grips. Then, I've truly achieved Glock Perfection. Next up for me is a G34... which brought me back to the Classifieds... which led to my "other" post getting locked. My apologies, I wasn't trying to start a urination competition.
