I just checked my Hornady manual and it doesn't list Tite Group for the 124 grain XTP. Based on my experience with Hornady's data, which I have found to be excellent, I believe that it can be inferred that Tite Group is not a suitable powder for this bullet. Trend wise the data listed powders with burn rates similar to Unique, so I would suggest looking in your powder stash for something slower than Tite Group.
I load mine a little short at 1.150". You're just into the +P range, which is why it's not in the standard 9mm tables.
Titegroup is listed in tested loads up to the 147gr XTP at 3.6gr.
Titegroup is a favorite powder with the action pistol group such as frequent the Brian Enos forum.
If you're new to reloading, don't get all wrapped up with COL varying from table to table: that's just what they used that day. That length or anything longer is fine for that data if you pistol will chamber it.

I load my berrys 124 at 1.150 but hornady list there at 1.060 sounds real short?.....maybe I,ll try 1.100.
It does seem sort of short for a 124gr xtp bullet when Hornady's
data for the very little 90gr xtp bullet has a OAL of.......
are you ready for this.............
C.O.L. 1.070"
My Minimum OAL with a 115gr RN plated is 1.10" to keep the
case from passing the bullets Ogive.

The Hornady 9mm bullets have a more abrupt shoulder at the start of the taper than most other bullet makes that have a more gradual taper. Loading the bullet long can result in failure to chamber properly if your pistols has short lead and that shoulder gets into the rifling before fully chambering. The 1.060" OAL in the Hornady manual ensures reliable chambering. If you go longer do a plunk test in your pistols barrel(s) to make sure there's no issue before loading a bunch of rounds.

I think I should have gotten Sierra bullets instead because they list Titegroup from 3.7 to 4.4 col at 1.075 for JHP..might just have to use unique powder instead the other powder I have..
I LOAD THE HORNADY 115 & 124 XTP AT 1.142" OAL. THIS WAS FROM THE VV LOADING MANUAL. VERY ACCURATE. 115GR WITH 5.0GR VV330 OR 124GR WITH 4.8GR VV330. JP

Thanks ya for all the help...........
I load my 124gr XTPs to 1.115" for my 3914. It has a fairly standard sized 3rd Gen leade of .100".
Like Steve C mentioned, do a plunk test. And always do a plunk test when you first try a new bullet/style/weight. Then document that OAL" & refer it next time you load that exact bullet, & forego the plunk test.

The reason no data is the same is because no two guns are the same. Obviously, there is not ONE COL for that bullet. You can either work up a load with one of the COLs and, if it chambers, call it good or you can work out what COL is best for your gun(s). One place you can start, if you want to just "use some number" is start at 1.100" and work up or down until it feeds and chambers.
Per Ramshot:
"SPECIAL NOTE ON CARTRIDGE OVERALL LENGTH "COL"
It is important to note that the SAAMI "COL" values are for the firearms and ammunition manufacturers industry and must be seen as a guideline only.
The individual reloader is free to adjust this dimension to suit their particular firearm-component-weapon combination.
This parameter is determined by various dimensions such as
1) magazine length (space),
2) freebore-lead dimensions of
the barrel,
3) ogive or profile of the projectile and
4) position of cannelure or crimp groove.
• Always begin loading at the minimum "Start Load".
• Increase in 2% increments towards the Maximum Load.
• Watch for signs of excessive pressure.
• Never exceed the Maximum Load."
Your COL (OAL) is determined by your barrel (chamber and throat dimensions) and your gun (feed ramp) and your magazine (COL that fits magazine and when the magazine lips release the round for feeding) and the PARTICULAR bullet you are using. What worked in a pressure barrel or the lab's gun or in my gun has very little to do with what will work best in your gun.
Take the barrel out of the gun. Create two inert dummy rounds (no powder or primer) at max COL and remove enough case mouth flare for rounds to chamber (you can determine this by using an empty sized case, expand and flare, and remove the flare just until the case "plunks" in the barrel).
Drop the inert rounds in and decrease the COL until they chamber completely. This will be your "max" effective COL. I prefer to have the case head flush with the barrel hood.
You can also do this for any chambering problems you have. Remove the barrel and drop rounds in until you find one that won't chamber. Take that round and "paint" the bullet and case black with Magic Marker or other marker. Drop round in barrel (or gage) and rotate it back-and-forth.
Remove and inspect the round:
1) scratches on bullet--COL is too long
2) scratches on edge of the case mouth--insufficient crimp
3) scratches just below the case mouth--too much crimp, you're crushing the case
4) scratches on case at base of bullet--bullet seated crooked due to insufficient case expansion (not case mouth flare) or improper seating stem fit
5) scratches on case just above extractor groove--case bulge not removed during sizing. May need a bulge buster.
