This is why I started my comment with praise for his actions and an attempt to address the tac reload separately as a technique being trained rather than the specific incident and it being used. I do not want to be critical of a single officer or two incident it is just that they appear to be examples of a tac reload or similar being used in actual gunfights/shooting incidents caught on camera to bring the incident to light. I don't know how to be more clear on seeing an example of something and discussing the technique while not being critical of the individuals who used the technique.
That said I have never said that tac reloads were not used in real gunfights and the 2 videos show it or variations of it. I also never said that topping off is a bad idea or cannot be done. My problem with the whole tac reload is that it is being taught in a way that ZERO evidence of ANY police or citizen concealed carry person has EVER performed one and then used the ammo they saved in the magazine retained. NONE,NEVER. Why teach a technique that in these 2 examples presented a compromised grip or delayed return to full capacity and functioning weapon when it takes time,effort and ammo to do and yet is still done or the person runs the risk of doing it improperly with extremely minimal benefit that has NEVER been needed. I just don't understand how to make the point clearer that there may just be a better way to do the same thing, that is topping off a partially loaded weapon after firing shots.
In both the listed incidents on video and any others that have been documented a better technique is the one demonstrated by Jon Corriea in the posted video he calls Proactive reload. It allows for shorter time between partial mag in gun to full mag in gun or at best equal time. The technique gets the support hand back on the gun faster, and it does not require any juggling of magazines or diverted attention to secure partially depleted magazine. For the increasing numbers of smaller stature officers(women and men) and the almost ubiquitous use of double stack guns by police and many citizens, the Tac reload adds complexity and dexterity factors where it isn't needed.
If there is a faster and easier way to accomplish the same task that works for a larger group of users and works more consistently with less change from normal or primary skill(the slide lock reload) why not do it? When is there enough reason and evidence that the time to change is now?
