Sorry about the bad experiences over there. Only issue I ever had was that it took several weeks to get a response back to my registration to the forum.
I have found them to helpful a time or two. Specifically when I was looking for a good Sig gunsmith in the Phoenix. I wanted an action job done on both a P226 & P239, just wanted them a little smoother.
They referred me to a master smith: Frank Glenn-Glenn Custom Complete Gunsmithing Service Glendale AZ
Gentleman by the name of Frank Glenn in north Phoenix. He works on everything but does most on 1911's offers a variety of packages on Sigs plus anything else you might need/want done.
Best referral for a gunsmith EVER.
