My wife's BuG is a Taurus revolver in .38 and recently the weapon has been giving us some issues. It will cycle fine sometimes and other times it will hang up pretty solidly. Well since she wanted a slightly lighter trigger pull I got some springs ordered and disassembled the weapon. After a good cleaning and open-sided reassembly I discovered the locking issue by accident; The hand pin is lodged in the back of the trigger. Some grit must have gotten in there and sunk it in to the point of immobility. The gun will fire perfectly...as long as you're aiming it at the ground. Getting a replacement is going to be a chore, I haven't been able to track either piece down. So if you've got a similar issue showing up on your Taurus revolver this could be the culprit!
