What is the best ammo to use in a Glock 17?

The G17 is chambered for 9x19mm, also known as 9mm Luger, 9mm Parabellum, and just plain 9mm. “NATO” is 9x19mm ammunition that has a 124 grain FMJ bullet loaded for higher velocity. It will work well, and as EdF702 mentioned, it's a good idea to break the pistol in with this high energy ammunition.

Best Ammo to Use in a Glock 17 Gen 5

I'd recommend sticking to a 115 or 124gr bullet in your G17. They feed reliably and are effective. I have personally seen people use up to 147gr but finding heavier weights can be a challenge and it's always best to keep things consistent.
