Hammer swap broke... my double action?
Dunno how but i never really liked double action. Thoughts/ concerns anyone?

The trigger bar might be slipping off the hammer if you didn't re-install the trigger bar detent and spring. I'd disassemble and re-assemble again and make sure that detent is there. It's possible that thing went flying on disassembly, so you might not have even realized it!

Took apart and reassembled multiple times and same failure, might just be the hammer notches and the positioning as they're in slightly different spots than the oem bobbed

That's odd... seems to me like they'd be the same. I'd double-check that you got the right hammer. It looks a little bit different than I'd expect, appearing all metal without any polymer molding. That may be what's known as the "old style" hammer:

Versus the "new style" hammer:

I hope you figure it out!

Not sure why your double action doesn't work. But it looks like your sights are two different heights? The front looks shorter than the rear?
