Customer Service is always nice to have but better yet is a product that needs no service . It really is hard to imagine so many happy shooters that need to send a new gun back to the factory . It tells me one the factory is not making a quality product and two their customers do not really shoot the product that much . Old saying junk in junk out .
You're living in fantasy land if you thing something can be made that needs no service. If it's made, it can and will break. The secret is to make the breakdown as painless as possible.
I stopped along an interstate to assist someone whose car had broken down. The owner was remarkably calm and understanding considering he was driving a new Rolls Royce. He had called Rolls Royce and customer service had calmed his fears. It showed me that the most important thing when a problem happens is how the manufacturer handles it.
