for the life of me see how any of these are "clean"[/QUOTE]
I use Titegroup for 40 SW and VV for 38 Super. It's hard to believe how much cleaner the Super is after shooting it as compared to the 40. I never thought there could be such a difference until I saw it with my own eyes. I don't how they do it - but I know what I see. A lot of top USPSA competitors use VV. Reliability is everything in USPSA and all things being equal, a clean gun is more reliable. That being said, I'm very happy with Titegroup and will continue to use it in the 40.
