Looking from the edge of the crown to the outside diameter of the barrel, notice the difference in thickness from the left side (thicker) than the right side (thinner). Should I be concerned about this? Many, many thanks to anyone who can help with this.

I have 2 of them when I get home I will check mine and let you know what I find

No !! The only important thing is the actual crown , that is the junction of the rifling and front of the barrel. Shoot it and enjoy. Make sure to try different loads as your gun will prefer some over others.

It is just the land is on one side and the groove is on the other, so it looks like there is a big difference in thickness. I cannot imagine there is a strength issue there and would not be worried about that.

After measuring it I find that one side is, in fact, thicker on one side than the other even discounting the lands and grooves. Now what?

Shooting Time, thanks very much. I'll check in tonight on this forum.

However, since the forcing cone is a physical part of the barrel wouldn't it not produce an even distance all the way around from the cylinder (uneven cylinder gap) if the barrel were crooked?
In other words, since the cylinder/forcing cone gap is nice and even all the way around does this suggest that the actual bore is straight even though the steel around the bore may not be even?

No, I've seen that on any number of handguns. Machining being what it is, or isn't, you'll rarely see a perfect barrel. I used to think it was me eyes playin' tricking on me, but tain't so. It is a teeeny bit off, but they generally try to make it a little more towards the top than to the side, but it's only cosmetic.

One of mine measures .422 on the left and .428 on the right the other 426 & 430 that is in the groove to the outside of the bbl hope that helps you out

Shooting time, would you mind posting a picture?

If you have accuracy problems then it may be the reason, if no accuracy problem I would not worry too much about it. If you have accuracy problems call S&W.

The crown is a bit off center.
It it's accurate and you can adjust the sights to get the POA and POI in agreement then it's a non-issue. I'd be surprised if it causes a problem.
