I scout carry my 3, PR4 and my JG3 usually, but I slightly changed my carry on my JG3 based off a suggestion from Justin Vititoe.
My preferred carry for anything with a blade over 3.5" is 45 degree cross draw. It's such a natural movement.
Trying to find a good solution for a more horizontal carry on my 6HM...when i figure itnout ill let you know.
