I have a Taurus M669 and I discovered that Aimtech made an AMST1 mount for these revolvers requiring no drilling. However, it looks like they quit making them but I am guessing somewhere someone has one in a shop or a gunsmith shop, just someplace they would like to sell. This is my last attempt to find one before I sell the gun. I love my Taurus and love the accuracy of this .357 but I want a scope mounted for hunting. But I need to find one of these mounts and also had asked if the mounts for a S&W might also fit and be adapted but customer service for some companies is nonexistent these days!
