Alright, I've:
-softened the edges of the hammer
-polished the rails, bolt carrier, and hammer
-installed the DPH gas plug and CSS puck, decided to put the performance recoil spring aside for now
-threw in a buffer just in case
The results? I've had one hangup out of about 50 bulk target loads so far but otherwise she's running flawlessly.
Only thing left to do is run a few hundred through to break her in fully and learn to manage recoil just a bit better, hah.
