Sorry about referring to the cartridge as a bullet. Not sure what I was thinking, I do know the difference.
Welcome to THR.
Don't worry, in time you'll get the hang of the reloading terminologies. I try to remind myself to use the proper terms like "cartridge" for assembled rounds and "projectile" for bullets but often prefer to just call them rounds and bullets.

If you don't have a manual, YOU NEED TO STOP right now & get one. Every manual has the info you're looking for.
Dang, I think you should cut blitztech some slack. He did mention in his original post that he already had a manual.

The manual I have shows a cartridge length of 1.169"
1.169" ... Do all 9mm cartridges have to be this length or is there a minimum and maximum cartridge length that I'm not aware of?
As others posted, no. And using the listed OAL in the published load data won't ensure it will work in your pistol to reliably feed/chamber from the magazine as different brands and models of pistols will require different OALs to work reliably with any particular bullet.
The two lengths you should learn to determine when working with any new bullet are:
1. Maximum Overall Length (OAL) also called Cartridge Overall Length (COL) and
2. Working OAL
Max OAL is the longest length of the finished round/cartridge that will fully chamber in your pistol's barrel without the bullet nose (ogive) or the bearing surface (part of the bullet base that rides the rifling) hitting the start of rifling. Walkalong has an excellent thread on using the "barrel drop test" to determine the Max OAL -

Working OAL is the length of the finished round that will reliably feed and chamber from the magazine. For some pistols, working OAL can be the same as max OAL but sometimes shorter than the max OAL. I have outlined the step by steps to determine the max/working OALs in Walkalong's thread on this post (scroll below the pictures of barrels) -

The problem I'm having is with the 115 gr 9mm I'm using there is a gap just below that length when seated and the bullet wiggles around.
I am not sure what you mean by "a gap just below that length when seated".
As to the "round/cartridge" wiggling around when chambered, this is normal for most factory barrels. For many "combat" style pistols (like Glock, M&P, etc.) meant to operate with some amount of fouling build up, chamber and mouth are tapered or cut looser and the chambered round will "wiggle" a bit. Don't worry though as the forward part of the chamber dimension is what seals with the case mouth/neck when the powder ignites.
Once again, welcome to THR and hope you enjoy your stay.
