I dont have a pistol scope but have a rifle scope. Bought it back in 91 had it on my muzzloader for years and on a an ithaca 37 12 guage,then on a 270 rifle. At around 20 years old it gave up a lens 5 days before deer season. I called customer service for warranty info, and the lady sent me a brand new scope in 3 days with a return mailer for the old scope. Cant speak to the pistol scope but there customer service is a number one.
