Hi Viz sights are great. Make sure you have some FO filaments handy.
One tip, and I know it's a personal preference, get a red front post and blacked out rears. If you get the green tritium rears and the red FO front, the sight picture gets very confusing especially if you already have eyesight issues.
The hi viz red front/ black rear combo is very easy to see quickly for sport shooting.
Also, when you have 3 green glows, it also makes quick acquisition difficult. Like I said, personal preference may vary!
Nice gun btw!
