Check the spring that sits in your striker block. If it's misaligned it can cause issues with your slide not moving completely forward during trigger reset.
Bingo! Thanks chrischris!! I stripped down the slide and when I pulled the firing pin safety, the spring appeared to be laying in the hole sideways. I reassembled without the safety or spring and the trigger reset fine. Once completely reassembled, everything worked fine upon function test.
I then went to the range to check function and the 115g WWB functioned better but still had some stove pipes and misfeeds. The Speer GD 124g+P functioned well, but there was still one misfeed in the 75 rounds I fired.
I zeroed at 25 yds and the 124g+P was still hitting roughly POA/POI at 100 yds. It was around zero degrees here today, so I didn't spend that much time on the 100yd steel!
Also on an interesting note, at 3yds doing Dot Torture I had to account for mechanical offset which isn't something I've seen discussed with the pistol RDS. I'm sure it's more pronounced in the Balor/T1 setup than in a milled RMR slide. (And not that 1" at 3yds really matters...) I stepped the target back to 7yds and it was close to POA/POI, as much as my frozen hands could tell.
I'll post something on the FB Primary group and see if there's any more response on the lower weight recoil springs.
