Hello all; I am wanting to upgrade the sights on my Colt Combat Commander. I have settled on the Novak Tritium wide Notch rear and the Triutim Mega-dot front. My 55 year old eyes are not what they usde to be and I am hopeing this set-up will fit the bill.! Anyone with any experience with this system could you plase join the conversation. Thank-you in advance for your consideration.
