New Wilson Combat Extended Thumb Safety. Part number #6BN. Blue, narrow thumb pad. It has never touched a gun. I purchased for a competition gun not realizing it was a narrow pad.
$25 shipped first class US.
Black Nitride, from a brand NEW NH Falcon Commander, never fired, replaced as soon as I got the gun with an Ambi-Safety. This is a $75 part without the Nitride. $60 Paypal F&F SHIPPED
