Hey everyone I'm new to this site and wantdo to get so excited info from ya'll. I have a TRP Operator and I don't like the adjustable sights because I just can't see them well. I just ordered the U notch rear sight from 10-8 Performance (great sights by the way I have their U notch rear sights on all my carry pistols) but 10-8 does not provide a front sight that fits. Question is what are the measurements of the cut and front sight height? I'm looking for a nice red fiber optic frontsight. If anyone can point me where I could get one and or the measurements that would be great. Thanks everyone.
