+1 on Trijicon. I have had them on many handguns and have had zero issues.Trijicons are the industry standard for a reason. I've seen people have issues with TFO's on more than one occasion.
Would have to agree shot with them for the first time last week in a dimmly lit indoor range but could pick up the sights very easily...at one point had my kids shut the lights off in the range and they were glowing bright.Alright so I went to the range today, went thru 150 rounds, and these sights are great. I found them easier to get on target than the stock sights, and are brighter on the dimly lit inside range I shoot at. I would recomend them to anyone, at this point.
