Newbie here with questions... What does the matching rear (blacked out sight) get you? I understand the blacked out concept, and just planned on taking a black Sharpie to my stock rear sight & using the saved $14 on more ammo. If there are benefits to getting the set, what are they? Also, are adjustments needed after the new front sight is put on, or is it fixed? Finally, how long can one expect the tritium to last?

BTW - my stock front sight white dot fell out after about 50 rounds through my new M&P9. Local gun shop where I bought it took care of me. Point is, I would actually have more faith in an after market sight since their sole focus is the sight (whereas S&W is focused on all parts and therefore more likely to have minor glitches).
