I saw this on another forum but had to check it out for myself. This is from the EAA website.

1) SAFETY UPGRADE NOTICE
If you own an EAA Witness style semi-automatic pistol bearing a serial number between
AE00000 to AE70000, please read this Notice.
Owners of the above designated Witness pistols should immediately field strip the pistol and send the slide assembly to European American Armory Corp., 411 Hawk Street, Rockledge, Florida 32955. Upon receipt, European American Armory Corp. will replace the original firing pin with an upgraded firing pin for your pistol.
Please follow the instructions and warnings in the Owners’ Manual and do not disassemble your pistol beyond a field strip. Any disassembly beyond a field strip should only be performed by a qualified gunsmith. In particular, the firing pin should never be removed by you. If the firing pin is removed, it must be re-installed correctly by a qualified gunsmith or the EAA Corp. service center. If the firing pin is installed incorrectly in an upside down position, it may adversely affect the operation of your pistol and its safeties. If your pistol is not operating properly, discontinue using it and take it to a qualified gunsmith or send it to the European American Armory Corp. service center immediately.
Thank you for your attention to this Notice. Please call European American Armory Corp. at (800) 536-4442 if you have any questions regarding this Notice.
