for the tool to remove the factory sights. There is a review tab that will also provide some information. Then buy the adjustable sights http://www.berettausa.com/products/p...-sight/e00457/
Also check out the review tab, seems hit or miss (like this pun). Before you put the money into something that should work to begin with, keep sending it to Beretta until they get it right. Before you send it, check to ensure they have your warranty card on file. They are way behind on the cards as well as the rebates due to volume of purchases. Also have some one else who is a good shot try the gun. Might be a grip vs finger pull issue or eye sight perspective. Especially with glasses.
