Traded a pimp'd out Remmy 870 for a used (2009 era) Taurus PT 1911 AR. Blued. Got a few questions: What should I look for to make sure nothing needs replacing? What are some good sites to get recoil springs, hammer springs, upgrades? I really want to replace the recoil spring right off. Will it run any average full size 1911 recoil spring? (I'm just weird that way) Thanks for replies, in advance!
