Taurus PT24/7 PRO DS sights ?

[yetii]

I have a Taurus PT24/7 PRO DS in .40cal, my question is does anyone know if the sights on this gun are interchangable with any other guns sights, i want to replace with a different set but am unable to find any replacements. Any info would be greatly appreciated, and if this is in the worng sub-forum please feel free to move it mods. Thanks Eric
