I have a 357 accusport bisley. I wasn't very happy with it's accuracy. At 25 yards off bags I was getting 2 to 3 inch groups, after quite a bit of shooting. I put on a 2 power scope with a clamp on mount just to see if it would shoot or the problem was me. It was definitely me. It easily shoots under an inch at 25 yards with several loads. Just wondering what sights are out there that will allow me to shoot more accurately than the big square ones that come with it. Also are there any disadvantages to them in the field. I also have a 44 accusport that I would change sights on if there are better ones.
