That seems cheaper than buying a new Glock 29, new barrel, and night sights.
May be cheaper, but at least you'd own two firearms! With your 20 being the c model, I'd almost bet you would even see less velocity loss going to a G29.
Wait for a used G29, and the money you'll save over buying new you can use for the night sights. Win/win!
