Odd S2 issue: What did I do?

[Sliv2]

I detail stripped my backup gun to do some light polishing. Gun is entirely functional in its current state: DA works, SA works, trigger resets, etc. 

HOWEVER, the hammer will not manually lower without some serious fiddling (mostly some form of pushing the hammer forward with my thumb). If I do my usual thumb roll method, or trying the "pinch" method, the hammer stays all the way to the rear and will not move forward.

 

Obviously, I need to disassemble the gun again to remedy the issue. But, for future reference... what the heck did I do? I'd like to avoid repeating the error in the future

Check the trigger bar lifter spring to make sure that it’s not caught on the side or out of place on the trigger bar.

Also check to see if any of the hammer strut pin is still flush on both sides.  They should be staked but if they move slightly they can move out and cause binding.

Good catch. I'll be sure to check that.

Just wanted to share that this fixed it. It only required about a quarter turn, but it worked. 

 

Thanks!
