Wiha is the BMW of precision screwdrivers. :thumbsup:I use Wiha for camera repairs.
Very nice precision tools.
+1 for Brownell's!Brownells sells a nice set of Magna-Tip bits and handles
Beyond that you'll likely find the need for other specialty tools and jigs. Brownells will likely have all you want or need.
I'd like to find some quality Torx head screws to replace slotted types.Ruger uses pretty standard screws with a few exceptions. My new Wrangler uses a T-15 Torks for the five grip frame screws.
For Bisleys, the screws on either side of the hammer are Allen head. There are some special application screws in Rugers to include the left hand thread slotted nut inside the center hole of GP100s (and other DAs cylinders).
Another is the split screw that holds the base pin spring on all SAs. You probably won't find these split tip screwdriver bits in any kit but Brownell's sells them.
