You're likely going to have to find that online and order it blind. Many shops don't want to take the financial liability of an extremely niche product that will likely sit on their shelves for a while and only get fondled occasionally, but enough to generate enough of a turn line that purists won't want THAT one (will want a fresh in box new one), and most other people will get turned off by .45 instead of .44 or a more common chambering, or who will find the birds head with the shitty thin "gunfighter" grips horrible, etc.
Thats how it worked what seems like a lifetime ago when I ran a counter, and is likely how it still works today with most independent shops.
That that is a TALO exclusive probably doesn't help, as it crimps down on the supply side of things as well.
