I put this on my Ruger Redhawk 44 mag.
Took it out to my range to sight it in and the front lense shattered after the only the 3rd shot. Optics Planet is being great about returning the item but I definately won't be buying another one and wouldn't recommend it for anything with a high recoil.
Pros: easy set-up and use
Cons: not shock resistant like it says
