HDS,
All of my screws were easy to unscrew. I wonder if firing a couple of hundred rounds through it helped loosen them up some. Also, I have a set of screw drivers from Brownell's that fit the screw heads. I think this is half the battle. You are right in that it is a little frustrating trying to get the cylinder latch spring and the pawl spring in place when reassembling the revolver. I think in the future for cleaning, I'll just take the grip frame off and spray with ballistol moose milk and then air blow the internal workings out instead of completely disassembling the revolver. Still have to deal with the two springs though.
Ten Wolves gives good advice concerning the screw drivers and gate spring clamp holder. I think I will order one in next Brownell's order.
Enjoy your New Vaquero.
