A little cleaning up still to do, but this time around, some further mods:
1. Determine exactly what steel the frame is made of
2. Anneal, then properly harden for max toughness
3. Refine the beavertail with feedback from the first. This one is 1/16th longer, and less radiused on the end.
Some pics to get started -
Next, front strap and trigger guard, and welding up the rails.
Starting with a KKM bbl, and will induction anneal the bbl foot for increased toughness.
