Recently, I purchased some of Magpul Dynamics training video series. They are top notch!
Travis Hailey and Chris Costa both recommend taking a split second to assess a malfunction type; then go directly to to appropriate clearing technique. For example, see you have a stove pipe, you sweep the case out and resume shooting. You do not waste time with a tap and rack. The thought is that the quick assessment and appropriate clearing technique is more efficient and gets you back in action quicker.
The technique I use is go directly to a tap, rack, & assess without any effort to identify the cause of the malfunction. If that does not work go to unload reload technique. The reason I have used this is a belief it is most efficient. Also, I attempt to keep my eye on the threat and employ lateral movement.
One problem I have with my current technique is I do not always know the malfunction I had to assess the likelihood of a malfunction.
I would like to hear your experience and opinions on what you do and why.
Take Care
