I find the orientation wording a little alien. Which one do I want to carry on my left side and access with my left hand?
From the website:
"
Choosing Carrier Orientation: Choose Strong Side Shooting Hand (carriers will be opposite side) Example: Right-Handed Shooters, choose Right Hand Strong Side Carriers. They are worn on the weak, or left hip."
Basic idea is that they assume you'll carry on your weak side AND access with your weak hand. (As opposed to cross-drawing your mags.) When ordering, list what your strong side is, and they'll make the choice accordingly.
For you, if you meant that the mag would be placed on your left side and grabbed with your left hand, choose Right Hand Strong Side Carriers.
