Reinstalling the hand spring retaining screw on a Uberti revolver is a pain in the neck. I keep extra screws on hand because they’re too tiny to grip while installing and are also spring loaded. Only my granddaughter can find them when they fly across the room. Today, I figured out a trick to not only guide the screw on but also keep it contained while setting it. All it takes is the spring from a ball point pen. Place the ball point pen spring around the hand spring and using a dab of grease to hold the screw on the driver top, insert the screwdriver shaft into the pen spring, compress, and start turning. The inside diameter of the pen spring contains the driver shaft and screw. If the screw slips off, it’s contained and you start over. No more mini Scud Missiles
