I picked up a Colt Model O 1918 that was made in 2008. I have to replace the thumb safety that Colt has a recall on. I called Colt and they looked up the serial number and said it hasn't been done. So I bought a wilson combat retro thumb safety and will have my local gunsmith fit it. I didn't want to send it back to Colt if I don't have to. They would have it for 6 weeks they told me.DSCN0957.jpg
