My P-11 likes Cor-Bon Pow'r Ball, Hornady Critical Defense, and my practice hand loads using Ranier 124-gr plated HP as long as I load them to 1.1" overall length. It tends not to like hollow point projectiles loaded over 1.1".
It can be finicky feeding Speer Gold Dot 124 gr, which is loaded to about 1.125" overall. I keep Gold Dot in the chamber (where feeding is not a concern) and it seems not to mind feeding them further down in the magazine. It just doesn't like them in the first four slots or so.
The main thing is to test your desired carry ammo in your weapon until you are satisfied and confident. I know it is expensive to shoot much of the self-defense ammo you intend to carry, but it is necessary.
