Taylor's & Co. Is my go to if your're looking for top notch quality, check out their Schofield offering online. You pay for what you get no doubt, but well worth it. My 1858 Remington conversion is in a class of it's own.
I believe they're offerings include 38spl, 44-40 and 45LC.
I got mine through the fine folks at Wolverine, I'm sure they would bring you one in.
