I picked up a used G17 that had aftermarket sights installed. I tried them a couple of times at the range, but I'm just not happy with the sight picture they provide.. I'd like less 'space' around the front sight. I'm looking for suggestions on replacing either the rear or front sight to tighten up the sight picture. I'd rather not replace both if I don't need to.
