A major Fed agency has SIG Armorers working to replace the firing pin positioning pin in all of their affected weapons, including picking up the tab on shipping the firearms back and forth across the country. Other agencies are looking into this as well.
I found all that with a quick google search.
What insight do you have into the actual issue, or are you just posting the same warning on every gun board?
A spiral (snail) pin is not the same as a roll pin as much as a roll pin is not the same as a solid pin.
