When practicing your reload, doesn’t it make more sense for real-world application if you don’t know when the bullets are going to run out? Rob Pincus demonstrates a training exercise you can use to keep your reflexes sharp. Typically, when you are at the range and have two full magazines prepared so you can practice your quick reload, you know how many bullets you’ve fired and when there will be slide lock, so you have essentially choreographed your reload. But if you randomize the number of rounds in each magazine, you are not expecting slide lock and train your body to react to the stimulus on the fly. Try this technique for yourself and see how the variable stimulus affects your reload response.
