FedEx came through...was hoping to shoot tonight, but it'll have to be in the morning. Cycles through dummy rounds fantastically. Might take it to GS tomorrow and get the night sights pressed in. I'll probably let them tune up their trigger. Got a few more small parts to hunt down. Might switch out the pins to black. I already picked those up, but I'm going to run a few rounds through it first and see how it functions.
I put the 3lb spring in. It's light, but it's all the way against the back before it clicks...not a pistol guy really, so I don't know if that's right or not. Almost feels like I'm out of room to pull - then click. Reset is super short and very audible. Here she is propped up on a chunk of wood.
