I know of only one source in North America for vegetable-tanned horsehide, Horween's in New York. Their production is limited and usually goes to standing orders of long-term customers in the shoe industry (also in demand for baseball manufacturing).

What is available to other users is very limited and usually does not include the most desirable portions of the hides.

Veg-tanned horsehide is very durable, being far more dense than cowhide. This poses challenges for use in holster making, being more labor demanding at every stage of production. So, in addition to competing for very limited quantities the purchaser is also facing higher production costs.

During my years in the business I could never get enough good horsehide to meet all demands.
