Before the ammo riot shortage I shot and stocked up with PRECISIONONE Plus P. I use it for carry and Break in. I also stocked up on the standard ammo for range work. However I also shoot other varieties of ammo like Remington etc. For myself the PrecisionOne give the best accuracy results with both the Pico and the Kahr. Never had a failure of any kind.
Here is the test result from about 5 years ago with just the STANDARD AMMO (before they came out with the PlusP.
