TEDNA…

You need to have the right pins for the triggers, mine worked great with the Wilson combat anti-walk pins. No wiggles.

If you are asking the pin size of the CMC trigger, it is a small pin size for this model. Hope that helps you.

I have the same question but what I would like to know is, what size is the hole dimension on the actual cmc trigger holes? Because a friend of mine has one of these installed and it wobbles in the receiver. If the holes are universal on all cmc triggers for large and small pins then all cmc triggers will have side to side play when using small pins, correct?
