Same height and with a high ride pancake holster I can conceal an original Vaquero. If you aren't dead set on 4 5/8" and plow handle grip, allow me to suggest a New Vaquero with a birdshead grip and 3 3/4" barrel. It conceals on my frame with a high ride pancake or even a Tom Threepersons. I normally open carry but occasionally half-hearted conceal. I have gone complete concealment with the Tom Threepersons but the pancake makes it much easier. If you aren't completely set on 357/38 then Talo offered a short birdshead New Vaquero in .45 ACP. I imagine there might still be plenty floating around on the market. It's my EDC and it is perfect for me.
