I am the kind of person that if somebody messes up I will tell everybody that will listen. By the same token if someone does a good job I will praise them just as well. I have had dealings with other companies especially Smith and Wesson, but Ruger definitely stands out in front with the quality of their product as well as their customer satisfaction. Recently I dug through the safe and found my dads old Mark II that had a red dot on it. Remembering how will they shoot, I wanted to give it a go with open sights again. So I proceeded to take the red dot off, and found that the rear sight had to be disassembled to mount the rail. After checking the local shops for replacement rear sight, I was not successful. So I called Ruger directly. I used Brownells website to get the part number and Ruger had the item for about $18 shipping included. Upon checkout, I asked if they gave an NRA or an instructor discount. The operator had to check with their supervisor and came back to tell me they would ship it out free of charge. That to me is impeccable customer service the way it used to be and the way it should be. I installed the rear sight yesterday and went to test it today. The target below is at 30 feet using Federal ammo. This is my way of spreading the word of how well Ruger conducts business and values their customers.
