Howdy. New to this site, spend most of my time over at GBO. Just bought me an older knight disc elite 45 cal .like a two didget #The gun is camo SS & in near perfect condition . It was the last thing in the world I needed. All ready have a omega X7 that I love. But wanted to try the 45 . Looks like a lot of guys switch out the breach plug so u don't have to use the red disc. Maybe next year, I'm a bit broke. Looking to shoot 180-200 grain bullets. Prob XTPs. I've got a bunch of .357 180 grains. But also looking at .40 200 grain gold dots. Any thoughts or experiences would be appreciated. Jay
