My trigger group pins fell out. Can I just replace them with std AR pins? And does the ZM/Para used a standard trigger group so I can drop a better trigger in?

And should I get a anti-walk setup?

On a more serious note, you might want to examine why the trigger pin fell out.  Properly assembled, neither the trigger pin nor the hammer pin should fall out unless they break, since they are both held in place by spring tension: the hammer spring holds the trigger pin in place, and the hammer pin retention clip holds the hammer pin in place.

Firearm will still function with a hammer spring installed incorrectly..but will cause the trigger pin to walk out. The Spring legs need to rest in the grooves in the hammer and trigger pins.

The pins had always been slightly loose and I would usually pop them back into proper place while shooting. But I was practicing some shoot and move on multiple targets a couple weekends ago and last night when I had the AR out practicing my dry fires, I noticed the trigger pull was horrible, and physically out of alignment. I tried to pop the pins back in but they fell into the lower.

I could put them back in, but I just think I will continue to have the issue. Maybe use a little thread locker or should they be allowed to move a little?

They won't move if the springs and pins are installed in the correct orientation. The springs prevent lateral travel of the pins.

If the trigger pins are walking on a standard trigger group something is either seriously wrong with your pins, your trigger group, or your installation. Do the legs of your hammer spring rest on top of the trigger pin with everything installed? one of the legs will sit in the off center groove on the pin and prevent it from walking. For the hammer pin, there is a spring clip inside of the hammer itself that snaps into the center groove of the pin and holds it in place.
