A CP Trinity trigger?...
It's either CP or Trinity (Since they're separate brands), and it depends on what gun it's actually for. If it's for an Ion it will fit an Ion. If it's for an Axe it will fit an Axe. If it's for a DM, it will fit a DM.
But, you can't buy a DM trigger and put it on an Ion or buy an Ion trigger and put it on an Axe.
You may call it fat, I call it bounce padding.
