I have a T/C peep site on my T/C Renegade .54 caliber. I think they have good and bad points. When the light conditions are good, they are excellent. You get a nice sight target/picture, and can make excellent shots even at long distances. When lighting is poor, they are sometimes hard to get a good site picture. Many times looking into a dark cedar thicket early or late in the day, it is hard to pick up the front site in the rear peep hole. I plan on putting a fiber optic front sight on it to help in this matter. On the other hand, I have a Traditions .50 caliber Hawkins with fiber optics, and I must admit the sights are easy to see and line up. Even in the early morning hours. I was raised on peep sights and shot them ever sence I could remember. My friend I hunt with put a peep on his CVA Hawkins, and HATES the thing, yet his son has a peep on his Hawkins, and would not use anything else. His is a Williams peep, and it is a nice sight. I think they are a personal preference. If you can find one and shoot them a little at different times of the day, and at different backgrounds... Good shooting to you..
