My pivot pin spring and detent will not fully seat.

Blasting media can sometimes get lodged in the pivot pin detent channel during the manufacturing processt. There is an easy solution to remove the media. Simply take a drill bit 2 mm or smaller with your fingers rotate the bit back and forth a few times then remove the media should fall out. Repeat until all the media is cleared and the bit is now skating on metal at the end of the channel.
