Slip-2000; Never noticed it on the shelf, attended a Glock Amorers course, a few years ago, instructor said he has been using it for years, even prior to working for Glock, Seems to work great for me.
If you want to shoot without getting oil on you, use one of the premium dry lubes or grease inside (I use Brownells Action Grease) and wax on the exterior non-moving parts for corrosion protection (I use Johnson's paste wax).
I have never liked mixing oil with sweat in a July match in OK.
