What aspect of the dehorning are you getting it done for? If it's so the pistol does not snag on your clothing or rip your hands up when you try to clear a stovepipe jam, then I say go for it, as that's what it's main purpose is.
Everyone has different tastes and if you like it and it doesn't have any adverse affects on the pistols accuracy or reliability and if you can afford to have it done, then go for it.
