All, I was out on the sporting clays course today with my 500 flex pump and the safety came loose and shut me down. After inspection in the man cave (garage) looks liker the safety retention screw Had loosened up to the point that the safety would engage every shot under recoil. Good news is that it started to pour rain and we high tailed it to the apres shoot watering hole anyway. Bottom line after careful inspection is that I need a new ball bearing detent for the safety mechanism. Anyone have some spares, I’ll pay for parts and US post.
