I'm a retired gunsmith, so maybe I can give a perspective from a gunsmiths point of view.
Any good smith is going to be backed up from 6 months to as much as a couple of years. The smith I now use has an advantage, 2 sons who have become darn good smiths from having worked with their father who is a master smith, he manages to keep work times at about 2 to 4 months ,give or take, most smiths do not have that advantage, hence the longer waits.
A smith should not promise what he cannot deliver. That said, there are times a smith can get behind. I've had jobs that should have been 1/2 hour jobs that took four, you also have interuptions from phone calls as well as customers coming into the shop.
Some smiths will only take e mails until it's time to work on the customers firearm, I didn't like to do business that way, customers should be talked to, but they should also realize that they should keep it short when they can. The guy who is told 2 months and calls every day for the last 3 weeks is a major pain in the butt, and it happens on a regular basis.
Gunsmithing is not an exact business, some guns go faster than expected, others will take longer, especially if it's a good smith who will not return your firearm until it's as good as it can be.
Where we are, we have long winters, there are times it may be 5 days until a gun can even be test fired, sometimes more, that slows things up sometimes.
The bottom line is that a smith should give an approx. time the firearm will be finished. If done before that time, it's fantastic, if it takes longer, that is just the way it is sometimes. You get hung up because a customer wants a specific brand and type of barrel and the barrel maker takes 4 months to get it to you. Things like that happen all the time. You try and order as soon as possible, but I have seen barrels take 6 months to arrive, not the smiths fault.
My smith had a death in the family, he had to leave the shop for 8 days. His sons did some work, but he does all the machine work, so it put him behind a week, time he was not expecting to be gone.
Most smiths are a one man business and have things come up just as we all do.
If the smith is honest, he will give you an approx. date, but things do happen that put things out further sometimes. It's hard when you have a 6 month back log to give a date and hold right to it at times. Other times it's ready before the date.
If you have found a smith that is honest, gives you a date and does his best to hold to it and does great work, you have found a gem, treat him like gold.
Don't keep calling asking about progress, if the smith says it will take more time, give him the time, especially if it's not his fault.
It's not easy being a smith, especially one who will never ship sub standard work. many times it's just little things that most shooters would never notice, but the smith knows and does his best to give you the best work he can.
Last, most smiths don't get paid what their work is worth, you have to know so much to be a really good smith, unless you have been one, you will never know. Gunsmithing is a labor of love, the love of firearms and precision work. I know my smith with all of his talents could make far more money doing something else, but he would not be happy, he loves what he does.
I'm not trying to make excuses, a good smith will be as honest with you as he can be, but do realize that sometimes things come up in his life as they do yours, things may take longer, it happens. Just don't be the guy calling all of the time if you have found an honest smith, when he's listening to you complain that the gun should have been there last week, he is not getting any work done, including yours.
If time runs over, a quick call is fine, but don't be one of the idiots that calls 4 times a week, it slows things down for everyone.
Not every smith is a good one. When you find a very good smith, work with him, your gun will get done as soon as he can get it to you. The only way for things to be done faster is to work more hours, most smiths I know work far more than a 40 hr work week, the other way is for the smith to work too fast and not give you and other the precision they require and expect. My smith will not cut corners for anything, yours should not either.
If you are ordering a custom rifle, pay for the parts up front, don't expect the smith to have to carry you for 4 or 6 months and be your bank, they are not rich, even the best of them with few exceptions.
Great work takes time, realize that. You can take your gun to a smith that will have it back in 2 weeks. Chances are, you are not getting very good work, yes sometimes, but in most cases, smiths that do the best work are booked, that's life. Some smiths will tell yo 8 months when they are 6 months out just in case something comes up or some firearms have taken longer than expected. Maybe that's the way all should do business, that way you are happy when you get your gun back sooner. I don't know how people feel about that. I tried to give the best estimate I could, I think that's better than telling you your firearm will take 2 or 3 months more than it most likely will.
You can decide if you think that is the right way to do business. It would make it far easier on the smith, that is for sure, but is it the right thing to do? Firearms get done as fast as the smith can get them done, just hope you find a smith that does not cut corners to get guns back faster, that I have seen happen.
If I had to take more time to get firearms done than promised, that was the way it was, you waited. I did my best to give good estimates of time, but life happens. When I got them back faster, all were happy. It's a hard thing to manage.
And I agree on not giving preference. There are times when someone brings a firearm in that need something that will take 15 minutes to 1/2 hour. I would do a small job like that rather than having a guy wait 6 months to get his scope mounted. Those are the exceptions I feel are reasonable, but not a major job, everone waits for those.
Since people are mentioning their favorite smiths, I have to mention mine.

A fantastic smith by the name of Scott Null, one who cares and works with his customers and does nothing but the best work.
He's located in Idaho. Honest as the day is long and a great guy to have do your work. Not one worry sending any firearm to him. Savage Corp thinks enough of him to have him be a part of their regular round tables with the CEO, engineers, production mgrs etc. He even builds custom rifles for the CEO.
My Best, John K
