I am looking at upgrading to a different open sight set-up for my Sidekick. I presently have the Williams Fire Sights that came with it, they work well out to about 50yds or so, but would like to find something that is a little more precise out to 100-125 yds, maybe a williams peep. I was wondering if anyone here on the forum has upgraded their sights and if so what worked for you. Thanks
