I stand corrected. I forgot I switched out the grips on my Tac Pac 1911 after the first outing to the wood ones that are on it now. I didn't know about the night sight difference. I guess since I am not a fan, I didn't miss or look for them when shopping around.The Tac Pac has plastic grips and white dot sights. The Nitron has wood grips and night sights.
