I purchased a new Ruger P-89, 9mm pistol some months ago, and am well satisfied with it. It is very accurate, and digests all the wide variety of ammo I have fired with it. I am thinking about having Millet sights installed. An adjustable white outline rear, and a white front blade. Dim lighting on many ranges I have shot on, out of the shooting booths, could be a help to me. I have fired a friends pistol, with the white outlined "fixed" Millets. But I think I will go for the "adjustable" ones. Has anyone on this web site been familiar with the adjustable Millets? They seem very high quality. I would appreciate any advice. Thanks.
