Reloading is a critical gunfighting skill. While it's not typically too useful for self defense it is very useful for practical shooting sports, where time factors into your score.
There are lots of things to like about this drill, including :
- Support hand is going for the fresh mag right away- that's the key to maximizing your speed on a slide-lock reload
- Reloading is an important fundamental- pulling back into your workspace and driving your weapon system back into the fight is a skill you can't practice often enough
