I have a $40 truglo four pin sight I have been using for well over a decade. With getting older my eyesight isn’t what it once was and my shooting has declined some because of it. Not trying to make it out that I am way off but I am definitely not as accurate as I was 5 years ago. Thinking of switching to a single pin sight. Having extra pins in the sight picture seem to be throwing me off a bit and under certain conditions I get a glare. Can anyone suggest a good sight ? What are the pros and cons of using a single pin ? I also welcome any suggestions other than a single pin sight. Looking to keep it under $150.
