You can get any of the handles (material-wise) that the shop has available, i.e.:
Leather
Walnut
Rosewood
Maple
Black micarta
Green micarta
Maroon micarta
Red & blie micarta
Ivorite micarta
Stag

You can have metal spacers to match the hilt color, etc. Butt caps are doable. I ordered a "commando" shaped and was turned down....It is what it is...and: YES, Stainless "is" available. Hope this helps
