9mm is on the list of my favorite calibers. The list goes on for the pro side. The negative side has recently been rectified with new types of bullets. I just picked up reloading dies for 9mm and plan on doing some experimenting. The G19 can take the punishment of +P or even +P+ loads. I don't want to push it to hard but I know with some balancing I can come up with a recipe that balances speed, power, and accuracy. All I need to do is get my hands on some loading components, cases, bullets, and powder, I already have small pistol primers.
