After some shooting with the new to me custom shadow, I've decided the front sight is still a little too wide for me. I'd also like to go to a serrated black and ditch the FO, but I don't see anything from Angus other than a black blank. Any suggestions? Mine measures .120 wide and I'd prefer .10 and I'm guessing it's the 6.5mm tall. I wish someone would come along wanting to swap.
