So I have a legion P226 DA/SA and a few VP9's one of which has been to Bruce Grey who did the trigger work on the legions. I have some gun time behind my Grey Guns VP9 and all I can say is don't sneeze. It is a super light trigger pull with excellent follow up for rapid shots. No gun time behind a SA P226 but my SA/SA legion is very nice as well. I believe it was $300 from bruce grey maybe a little cheaper to have him do the action job and polish everything.
It is an amazing gun and worth it in my opinion. Bruce grey and his team did an amazing job with the work, however they polish and re-coat everything as well. It is your money but, like I said my VP9 is amazing and like I stated early follow up shots are amazing, especially double taps. Just rock solid work from them.
Good luck in deciding. It's going to be a tough one!
