USMA/P, I just put the tritium big dot in front on my Ultra Carry for the reason you alluded. I have no practical experience, but in drills around the house & yard, the Dot was entirely sufficient. On the range, it works fine (good to 3 m).
OT, I was a 74E20 (Computer Operator) at the ACC (Thayer Hall) `71-`73. Is the Venice Bar & Grill still there? M2
