My standard 9mm load is a coated 125 gr. SNS bullet. All of my 9mm's shoot this load very well. I finally ventured into Glock territory with a purchase of my Glock 19. I was surprised at the lack of accuracy of my new handgun with my tried and true load. After a bit of study I purchased a replacement barrel from Brownells and what a difference! A vast improvement. The groups were about cut in half.
Moral of the story, the stock Glock barrel may not like lead reloads and a replacement barrel with cut rifling will fix the problem.
