Just because one has 15-20 rds on tap doesn't mean they are better served than having 8-10.
Sure it does. If there are 11 bad guys, 15-20 would be better. Or 6 bad guys you had to shoot twice. Or 4 bad guys that were moving and hard to hit. Or 3 bad guys wearing soft armor. Or 2 bad guys who needed suppressive fire.
More bullets and less reloading is always good. If somebody's of the mindset to "spray and pray" with 15 rounds, they're the same guy who's gonna spray and pray with 8 rounds. That's a software issue, not a hardware issue.
