Many thanks to Joel for sending out the new parts. (slide rod and sts) Got the parts yesterday and set everything up today. Never been much on fine tuning but today I decided to for the extra mile of perfection, after setting up center shot, I decided to go with paper tuning and shot once and didnt have to shoot again will post a pic later but very pleased with the results. Cable slide and sts for the silencer (2011) and can already notice the difference THANKS JOEL!!!!!
