I tried that stuff and gave up because I got tired of my gun not running in certain conditions etc.
My 3gun rifles now have H buffer and M16 carriers. Both have muzzle brakes. They run 100% now even when sideways or with 48 round mags.
Now the only difference in my competition guns vs. training/defensive guns is really just magnified optics vs. red dots and muzzle brakes vs. comps....not really much different. Train hard and often!
