I think most of the time your experience with a company depends upon the individual you are dealing with. I have been buying, selling, and collecting guns for 45 yrs. I have worked in two gunshops and had my own FFL for several years. I developed friendships with people at certain distributors and companies I knew I could count on. They would tell me what was available and what was not, and if not, how long it would take to get it. People like that are golden in any business. People good to their word.
There are also slugs employed out there who could give a rip about your service and would rather walk across a four way street to tell a lie when it would be easier to stand in front of you and tell the truth. A big company is always going to have a slug or two in the mix so your experiences will vary. I just think most people like to be told the truth about an order instead of being lied to. The slug will think how smart he is by telling you a big one and how dumb you are for beleiving him. At the least irritating and not in a small way.
