I have about 1500 rounds thru mine and no issues, I did change over to a SAO trigger and the pin seemed to slowly work it's way out after reinstalling so I staked one side and counter sunk it slightly to rectify temporarily but i dont completely trust it. CZ has a new version pin that is larger on one end that I was tempted to try but I have located a Cajun gunworks free floating pin that I should have shortly.
