Although advertised as such this sight does NOT fit the Ruger GP100. When compared to the stock front sight, it obviously has a longer base based and either needs to be cut or filed to fit. When the price exceeds $100 for the set, that is UNACCEPTABLE. Returning it right away - please do not advertise as fitting the GP100.
Cons: Does NOT fit Ruger GP100
