Nah. All my short barrels are DAO. As well, I carry my snubs iwb at about "1-o'clock". I have enough hair, fat, skin, clothing, etc.. to push out of the way to pull em. Don't need anything else working against me.
OK, the long nose is a nickle-plated 29-2, I just couldn't resist.
The one with Cocobolo grips is a 629-1. 2+15/16" barrel
629-3 Mountain Gun.
629-4, 2+15/16" barrel.
629-6 Trail Boss, unfluted cylinder with lanyard ring but no graphic. 3" barrel
