Picked up my first handgun a few weeks ago and went with the G19 gen4. In the past I have only had rifles and pretty much stuck with Remington ammo and that has worked well. From reading the forums here it seems that buying a large variety of ammo is a good way to go as Glocks need a thousand or so rounds through them to be considered broken in. So far I just have 100 rounds of cheap federal walmart ammo through this gun. I am wondering if anyone has any tips on what brand/type of ammo seems to mesh best with Glocks? There are so many brands out there, I was wondering what the popular choices are for cutting paper at the range and then what brand is most common among Law Enforcement? Thanks!
