While I wish there was a simple way to suggest a certain bullet, with a certain powder, at a certain charge weight, (at a certain OAL) to replicate a certain carry ammo load, but alas, it is not so simple..
If it mattered, a reloader could get Winchester cases and primers. The "Winchester" powder is a Hodgdon rebrand. Manufacturer's ammo is made with their own blends, not cannister powder for Joe Average to buy. There are many powders that will work well in 9mm, and while the "low flash" powder is real, how much it matters is debatable.
However, Winchester chooses not to sell any Ranger bullet as a component. Winchester Silvertips and plain JHP's are available. So a close replication of the Ranger ammo is not likely unless someone out there is selling pulled bullets.
So the question becomes a matter of what kind of JHP load do you want. If the answer is basically, "Just like the one I have." Then, a reloader needs to know what they have.
As in:
How heavy is the bullet?
Does is shoot to the elevation of your sights? If not, it may benefit to use a different bullet weight.
How fast is it going out of your G19? (The fps lie written on the box doesn't count.)
What is the composition of the bullet? Traditional cup and core, bonded, flex-tipped, barrier blind, depleted uranium, unobtainium, etc.
What are the terminal ballistics? (Almost everything has a gel test on youtube.)
If you know the weight and where it is shooting, at least you can have some idea of drop and recoil even if you don't know how fast the bullet is going.
We get back to where we started in bullet selection and talking about terminal ballistics. Here are typical choices for reloaders. Forgive me, if I have left out your favorite manufacturer or pulls that you bought somewhere. These are the typical, new in box branded JHP's. Most of these have been tested somewhere in ballistics gel, either at Lucky Gunner or on youtube.
Hornady XTP
Federal Hydra shok
Speer Gold Dot
Sig V Crown
Remington Golden Saber
Sierra Sports Master
Winchester Silvertip
...and other plain, unbranded JHP.
Some need a lot of velocity to expand. Some of these don't expand well at any velocity. Some lose their jackets. Some expand excellently in 9mm but overexpand and underpenetrate in 357sig. Etc.
