Kentucky Gun Co. is almost always the best source if online is ok. I also recently got a special laminate 457 scout from Sportsmen's Warehouse, again online.
KY Gun Co is your one-stop online shop with the lowest prices for firearms, ammunition, accessories, parts, and outdoor essentials. We ship fast and easy around the country from our home locations in Kentucky, and are always ready to help.
All my local shops seem to say nothing is available on the market for them to order maybe it's poor customer service idk. I've called shops as far east as Bangor Maine to Utah out west to far as Missouri south.
I was looking for one last year. Couldn't find one anywhere. I ended up getting a good deal on a 457 Scout in a local auction and adapted it to my needs. CZ seems to build and ship stuff in batches, and when they're off-cycle it's hard to find it anywhere.
