I have a Glock 17L that's slowly becoming a race gun. Among other things, I've added a threaded barrel and compensator. It has the lightest spring available but I'm still having ejection and feed problems. I tried a heavier grain bullet and solved the ejection problem, but the slide didn't come all the back so my feed problems persisted. I tried +p ammo and the gun fed pretty well until I shot too fast. I'm guessing +p+ would solve that problem. But the cost and availability of 9mm +p+ is a problem. I am starting to handload this week, mainly for the savings. I've searched for +p+ recipes and everyone seems against them. I was wondering if there is a powder or a powder/bullet weight combination that would kick the slide back far enough without having to load to excessively high pressures?
