Ok, here's the deal. I don't know if this is actually a problem, so I thought I'd ask you guys. Better safe than sorry!
I use a Hornady LNL Auto-Progressive to reload, and I noticed some inconsistencies on the overall length of 9mms
What I've found is, if a cartridge is being resized at the same time a bullet is being seated, it's not seated as deep as it is calibrated. Like the action of resizing is preventing the press from fully cycling
However, the difference is like 1.10 instead of 1.09. My thought is that this isn't enough of a difference to really be an issue, but I just want to make sure. I thought about calibrating to seat the bullet lower, but from what I understand 9mms can be touchy with pressures
If it matters, I'm using Rainier 115gr plated HPs with Hornady dies
If I left any key info out, let me know
Ruger Mark II 50th Anniversary .22lr
Sears & Roebuck .22lr

I don't have an LNL, but I do have a Dillon. As with any progressive press, you need to set each station for depth etc. with the machine full ie: All stations are in there normal operational state. Now as far as your OAL difference, it won't hurt anything.
Should not be enough to cause a problem.
A Wilson case guage will tell you quickly if a loaded round is going to be an issue.
I keep one on the bench for 9mm, .40, .45ACP.
If it fits into the Wilson, it will fit into your firearm.
You may find me dead in a ditch one day, but I will be up to my waist in spent rifle brass!
I got to thinking about it a little more and believe it is just the nature of a progressive press. THere is a little tolerance built in to the design so things can rotate. The difference you describe in OAL is not significant. .010 will not casue a noticeable difference in pressure, velocity, point of impact or cycling relaibility.
In life, strive to take the high road....It offers a better field of fire.
