I recently got a smokin' deal on a 44 spl flattop bisley NMB. because the former owner felt he needed a thinner front sight blade and used a grinder to "bubba-fy" the sight. Ruger wants a lot of $$$ to replace and re-blue the sight. Not a pristine example, so I'm not looking to invest in the cosmetics. I will be grateful for any ideas . . . Thanks
