A good belt, cinched up, is a good platform for Mexican carry.
I have always found it most comfortable at 3/4 on the strong side.
If you carry it cocked and locked--condition one--it is just as safe as a scabbard-----both require some due diligance in keeping the booger finger mindful of the trigger. That said, there are a couple of safeties that must be manipulated to engage the fireing.
You boys do it the way you want.
Blessings
