"I hate to be critical of your suggestion, especially since I did send my SW9VE to LSG and am very pleased with the results, but the FIRST thing anyone needs to do before sending your Sigma in to LSG is call them! I can not speak for Frank Smith, but I am pretty sure he does not want his FedEx account number openly published on the Internet and having you tell people to just send in their gun."
I can sure appreciate you looking out for someone's interest. Neighborly thing to do there.
Just to clarify: that's a direct cut-and-paste quote.
Frank posted those instructions on a public, online forum.
