On my attempt at a A. Verner styled pistol, I inlet the trigger guard spur with a bevel on the end of the rear tang, and it worked well, until the piece of maple holding the spur in its inlet popped out. Now the wood is missing and I need to install a wood screw through the tang ... should have done it that way in the first place. The spur on the end of a entry thimble tail, or on a trigger plate, where that is no tension, works perfectly. But where that is tension, as in the trigger guard tang,, some other kind of fastener is better. The grain flow in the grip at the end of the tang is literally cross-grained...not a good candidate for a retaining spur.
