Best sight for me - Xs Sight Systems Xs Front Sight Std Dot Tritium Green For Taurus 856/605

I have used XS sights for years. I especially like the green dot and have put them on every gun I have. I recently put the XS green dot sight on a revolver I just purchased. It made all of the difference in picking up the front sight quickly. The only problem I seem to have is the bright glow of the sight over shadows the gutter style rear sight machined into the top rail of the revolver. I am having a difficult time getting a precise shot. I consistently hit about a half inch to the right when aiming. I am close enough to the X, but not right on. The new sight is better than the stock black sight and the green dot allows me to quickly get on target. Close enough for up close self defense. There is no adjustment feature. The new sight sits in the slot of the stock sight.
