Sling for Mossberg 500?

[perpster]

I'd appreciate your recommendations on what sling to buy for my Mossberg 500 with 18.5" barrel.

I'm looking for sling to use for carry and for shooting, that will allow for quick transition to belt-holstered handgun in tactical/CQB situations.

I have swivel mounts on stock and magazine spring cover. I don't want to add a third swivel point (like for Ching Sling).

Thank you.

Would any of these be any good?
