I too strip them down first then lube/fire. Its kinda a double edged sword. The one time I decided I would just gas it up and fire it without inspecting everything I found a ball in the barrel the hard way...so did my computer monitor.
Another time I decided I would take a perfect working Vector all the way apart...I still dont know where that screw goes.
These days i'll "field strip" to lube and inspect, instead of tearing them all the way down. That is unless its someting I have taken down before. Ocasionally i'll buy a gun ive never dealt with just to tear apart.
