Hear are my thoughts. Four types of hollow points, but they don't have to be combat HP. You can get several brands of standard HP ammo, federal, win, hornady, rem, almost all makers sell a budget hollow point in 50 round boxes. Put a box or three, maybe four of these cheaper hollow points through it, then, imo, just practice a while with it and regular ball. Run a variety of these things through all of your magazines, don't worry too much about being completely consistent. Then, run a box of your chosen carry ammo, 20-25 rounds to be certain that it will also feed, that it shoots to proper point of aim. test for accuracy as well.
So, if you have cleaned and lubed up front, made sure that there are no obvious problems, there shouldn't be even a single failure. If you have any failures, go through it with a comb and find out what caused the failure, and fix it. Maybe it's just the particular ammo, and never use it again.
Some people say that a gun is never "proven" and others insist that there be many, many hundreds before they will carry it. Every time you take it out for practice, you are "proving" it again. after 200 rounds or so, with enough of them plain hollow points, I consider that well enough proven to start carrying, but not proven to the point that you can just stick it in the holster and call it good, never touching it again.
I don't think that I will ever consider my bodyguard "proven", its just to darned unreliable. so I try to keep the best cartridges in it and keep practicing.
Remember that there are only a few questions that decide reliability. Will it feed every time? will it fire every time? will it eject every time? will the magazine feed every time? is it accurate enough to hit a five inch target at 30 feet or so? that's about all that you need. being able to fire and being able to hit. This usually means that there is a question about the reliability of the ammunition as well.
