Searched the sites forum to see if this question was asked. Unfortunate for me it wasn't. I recently polished my g19 slide and thought new sites were needed. I carry and shoot at the range with it. I was thinking xs big dot but, being left eye dominant I keep thinking I need adjustable to bring the site over to my left eye. HELP! It's frustrating. I can shoot lefty but it's uncomfortable. I keep thinking just go lefty. If there is away to keep the Glock in my right hand and have sites to compensate I would love to hear it. Thanks all.
