I was shooting WWB 115 & 124gr and 50 rounds of Hornady 147gr critical duty. The Hornady was by far the most accurate and very negligible difference in felt recoil.
I love my Glock 19. There is a reason that it is the most recommended gun I can think of. Something about it just makes sense.
Glock 19 is a great gun. I shoot 147gr.
I have a G19 Gen 4and my carry ammo is Gold Dots 147gr. Shoot the best out of my gun after trying those, Federal HST 124gr, Winchester Ranger-T 147gr, and Federal 115gr Hydra Shok.
Great gun. Had 3 FTE in the first 150 rounds but after a thorough cleaning and lubrication, and another 800 rounds with no problems, I feel 100% confident in the weapon.
