Similar problem here. The trigger pin in my lower keeps backing itself out after every clip shot. 
DPMS LPK and POF lower.

Make sure the hammer spring legs are on top of the trigger pins. If they are you can use KNS pins to stop them from backing out.

They are, triple checked that they are on top and in the grooves. I'm hoping the pins are out of spec and not my nice POF lower.
Were you using roll pin punches or flat punches?I think I may have screwed the pin up...
It won't budge. Not in, not out.
I'd consider wrapping the jaws of pliers with electrical tape and just squeezing it in. You can always crush the roll pin itsself just slightly to make it slightly less tight.
Kinda' looked that way, if it makes you feel better I uglied up some of my pins on my first lower build with flat punches too 
ditto
had to beat the shit out of it
I think a lot of people are very cautious when hammering the roll pins. You gotta beat the shit out of them

You guys ever hear of a hydraulic press?
Oh, and +1 to roll pin punches. DO NOT try and use a flat punch to get that shit in there. As You've already noticed, doing so will only flare the end, creating the situation you have now. I'd just buy a new one and chalk it up as a learning experience..... I went through the same thing.

I got mine from Brownells.....
Don't know exactly what set it was... Looks just like these, but I know I didn't pay anywhere near that. I just told my smith to get me some. I'm thinking I paid around $20 for the kit, but it's been a long time ago.
Edit** probably works better if I include the link:

If you want to start tinkering with guns; go ahead and order some files, polishing stuff for a Dremel, punches, and proper screwdriver bits. Shit is expensive, but you'll fuck up a lot of stuff not having the right tools. Oh.. and especially if you want to do AR's, AK's, or any bigger project; Find someone who has a hydraulic press and buddy up with them. My last CZ (40B) was new, and the pins were staked and fucking stupid trying to get them out. 15 min and a press and all was well, with no damage to the gun.
