I'd pass on the Vision. The KP1's (if you can find one) are a better design even with the earlier trigger issues.
Yes, the breech plugs with the red FPJ can be made to shoot BH209, but it is more demanding. You should look for a better Knight rifle which has the BP with direct insertion of a 209 primer if you want to go the BH209 route.
Welcome to the campfire!
