You moved the goal posts, because your original premise seemed to ask whether one would buy adjustable sights. I cannot personalize a gun without adjustable sights, and barring a change in load, no...I don't have to revisit the setting once dialed in.
Not really. I buy revolvers with adjustable sights as well as fixed sights. I just happen to own more that have fixed sights. But if I find a real classic Smith or Colt with adjustable sights, I will buy it.
Here is an example. A .22 Colt Officer's Model Target made in 1935. This revolver has a relatively unusual arrangement for adjusting the sights. The rear sight is only adjustable for windage by turning the screw either direction.
For elevation there is a screw in the base of the front sight that raises or lowers the blade.
What I was really trying to get at was whether folks take advantage of the adjustable sights and actually adjust them. I fine tuned the question because I realized that I will often adjust the rear sight for me the first time I take a revolver to the range. I mentioned that in the first post.
What it seems from the answers I have gotten is a few shooters readjust the sights regularly, to optimize performance with various loads, but most shooters seem to be like me. Adjust the sights once for the load they usually shoot, and then they don't touch the sights again.
For what it's worth, when I took that Colt to the range for the first time I did bring along a tiny screw driver to adjust the sights, but it turned out it shot right to point of aim for me, so I did not adjust the sights.
While we're on the subject. The standard adjustable sights on a Smith & Wesson revolver have been the way they are for a pretty long time. Since shortly before WWII IIRC. But if you have a really old one, you need to bring along a really tiny screw driver if you want to adjust the sights.
This M&P Target Model (the precurser to both the K-38 and the Model 14) was made around 1917. There are two adjustment screws for windage, you loosen the one on the side you want the sight to move to, then you tighten the other one, shoving the sight over. Then you snug up the first screw.
This K-38 from 1950 has the modern 'click adjustable' rear sight we are all familiar with. This style of rear sight has always come with a nice big, easy to adjust screw.
