Theres the basics, then theres the basics of the basics and then there are the different variations on how you do the basics. I just got out of my garage after filming a few variations of the emergency reload. One would think, “how many ways are there to do a friggin emergency reload?” Well let me tell you.
This is how I was taught how to do it by my department back when I was a rookie. Physically strip the empty. Reload, then overhand sling-shot the slide. The reason for the selection of this technique was based on a known issue with Glock magazines. Some versions of the magazine were known to not drop free consistently. Rather than juggle a mag in the off-hand and then try to strip the hung-up magazine it was decided to strip the empty out before grabbing a fresh magazine. The slingshot technique was chosen because it is a gross motor movement, which was argued to be a better choice for a positive release under stress and possibly sweaty or blood soaked hands vs. trying to hit the small slide release.
With the advent of the newer Glock magazine…the ones with the metal tabs that contact the magazine release…
The drop-free issue is no longer much of a problem. So if you remove the “strip the old magazine” step you get this…
On the slide release issue; I decided to try a “strip..reload…slide release” and a “drop free..reload…slide release” to compare for speed:
Undoubtedly there is a speed advantage to the “drop free” and “slide release” technique, but I suppose that for the training of the average cop they are more skilled techniques with the potential for bobbling, dropping mags or missing slide levers. The question I am asking myself is what technique would be best for me to practice in general? I am still thinking about it.
