Jim, in my opinion the restoration would be cost prohibitive and even if you put it back it would still be a refinished gun and not original...
Should you choose to try this, there are two basic methods... both involve welding...
Method 1 is to build up the tang of the grip until enough steel is present for a metal craftsman to manufacture a stock lug...
Method 2 would be to obtain the relevant portion of a damaged Luger frame and have it welded onto your frame and then dressed down and refinished...
Unless the grind job is really ugly... just enjoy this gun as the shooter that it is... otherwise have the grip polished and refinished by THOR if you want it pretty...
Well, that's my
