I'm not a GS but I do stay at Holiday Inn sometimes and I still don't think I'd begin a new career working on a trigger job. Maybe install a recoil pad and work your way up. The one you got from the factory 'might' be faulty and you want to DIY a replacement? Put the thing in the closet or sell it and make it HIS problem, let a pro put in a Timney (he'll pay dealer and add bench time probably come out close to retail anyways) or wait a couple years for the rush to slack off. They will be fixing those recalls for two decades but by 2020 you can get in and out faster. I picked up a 600 that was never changed way back when and they returned it in about 10 days. jm2c
Ah, the sweet smell of burnt powder!
