Welcome!!!
I don't have any advice...Haven't been in SoCal in 40 years, so I can't help you with a smith...I use LSA on all my weapons, so I can't help you with lube...I have no idea what a takedown tool is...(maybe the mag helper tool?)...so I can't help you with that...I've gotten parts from Lugerdoc, Numrich, and SARCO, so I can't help you there...I field strip & remove cannon & subassemblies to clean; can't help you there...
I'm no help to you at all...
How about some pics of the pistol???
