If there is no +P on the box you have the standard pressure Speer Gold Dot load.
The CZ P-07 will handle +P ammo fine. If you read your owner's manual you will find a statement to the effect that +P+ ammo is not recommended and I suspect it would void the warranty. There will also be a statement to the effect that higher pressure +P loads can cause accelerated wear on the pistol, which is true but I suspect you would have to fire 1000s of rounds of +P before you saw a significant difference.
It is true that you won't find much difference in point of aim between different projectile weights and different ammunition at short ranges. I start to see a difference requiring a significant adjustment in sight picture at around 15 yrds or greater. I think one of the main advantages of using a practice round that closely approximates the muzzle velocity and energy of your self-defense rounds is to become familiar with the recoil characteristics.
I have generally stayed away from steel cased ammo like Tulammo and Wolf, but I have used a wide variety of brass cased 9mm ammo and not had any bad results, although I have found that point of aim can vary a good bit.
I have used Magtec, Prvi Partizan (Serbian), Blazer Brass, Remington UMC, American Eagle, Monarch brass (sold by Academy Sports), Winchester white box, Geco, Speer Lawman, Sellier Bellot, Aquila, Sumbro, and Federal CCI Independence. I have used other brands as well, these are just the ones I remember off the top of my head.
