Same here on the ammo but went up to 124 grain on the federalGlock19 said:G19. I use cheap Remington UMC ammo at the range and Federal (+P+ ) 115 grain JHP for defense. I read about this ammo on a law enforcement ballistics report online. That report mentioned a few different brands with similar specs. The Federal turned out to have a good deal on Cheaper Than Dirt. I love the 19, but am considering using .45 out of concerns about wall over penetration.
