Today's 9mm reloads are going to be 147grain round nose jackets. The bullet on the far right. The bullet next to it is a 115grain round nose jacket. In these shots you can see how drastically longer the 147 grain bullet is. You can also see one of these rounds is dipped, while the other has a real wrapped jacket. The wrap is a much higher quality.

Lots of people don't realize that a heavier bullet, actually requires less of a powder charge. The reason for this is because it takes it a fraction of a second longer to leave the casing mouth after the powder ignites, this causes the pressure in the shell to climb way higher then a lighter round, so if you don't reduce the charge, things will get ugly.

The faster a bullet moves, the faster it's going to spin. Because you're barrel spins every so many inches, as you increase speed, you also increase twist speed in a given distance the bullet travels. This increases centrifugal force being exerted on the round. Something to keep in mind when reloading for the perfect shot.
