I have narrowed my options down to the meprolights and the Glock Factory sights (which can be installed by glock for 57 bucks plus tax). I have heard that glock uses meprolight tubes in their sights. I guess my question really is...to you guys that have contrasting front and rear night sights, is it really worth the extra money to get orange/grn or yellow grn? Also, if you have any other recommendations as to what to put on this gun, feel free to recommend away, as I will always check on what yall say...and I will probably go back and forth on this purchase a few times anyways!
