Sometimes the thinnest portion of a part will through harden and this seemed to be the case in this situation. The client tried tapping the rear tang hole after the gun was re-hardened, popped off the section behind the hole. Had to weld that piece back on, torch draw and re-tap, make a new screw etc.

Hardening properly is the first consideration for me, looks second. I want a hard surface and a ductile core. Some shops do not see it this way.

I had to do the hard fitting on a Turnbull hardened boxlock for a client last year. The tang warped down substantially and the exterior was very hard. Because of the distance I needed to move the tang I torch drew it even though I know Turnbull draws his parts. I managed to move it to where it needed to be but it took some serious hard fitting. Not for the faint of heart but required at times.
