I’ve always lubed my guide rods in all my competition guns, which includes 2011s and glocks. The only time a Glock could potentially have issues running with too much lube is if it gets in the striker channel. Personally I lube my glocks heavily and have never had a single issue. I have seen plenty of glocks have stovepipes and other issues due to the guns being run dry. Running guns with minimal oil is never a good idea in my opinion. I have probably shot 60 or 70k through glocks with this method and have never had a single issue from it. The people saying they run theirs dry don’t shoot enough to know any better IMO.
