"Just take your time with the open sights and you'll get the hang of it." Easy for you to say - you young fart.
I had the "hang of it" with open sights long ago but, even though I can see the sights clearly in my mind, they just aint right out there on the barrel any more. Forward, aft, no matter - just doesn't work for me these days. I think more ofan animal than to shoot at oneusing irons nowadays.
