I believe Tri-Flow uses a suspension of Teflon. I really like Tri-Flow because it is a CLP which says it all. The last time I bought mine was probably something short of ten years ago at a gun shop. It lasts a long time. Another "tune-up in a can I really like the molydblenum disulfide (Mos2). It is a black grease. It works awsome on triggers. I think it was made by Outers but Mos2 grease should work. Its the same stuff they coat bullets with. Whe I used to shoot lots of IPSC the revolver guys would buy a new revolver clean and lube it all up and then cycle the trigger hundreds of times before deciding to working on the trigger.
