I'm inclided to think that Pentax is still one of those companies that won't put thier name on a product unless it'll do them proud. I've had a Pentax scope on my Super Redhawk now for over 10 years and it's been holding zero. I've also been considering the Nikon Prostaff and the Burris fullfield ll. For the money, it seems the Pentax is still the best deal, but the other two choices are in the ballpark also.
