New Weekend Knowledge Dump ...

 ... from Active Response Training. I always try and highlight a few of the links, so here goes:

• A Michael Bane podcast. I haven't had time yet to listen to the podcast (it's 52 minutes long), but Greg comments:

Michael Bane discusses how the “doctrine of the reasonable person” may no longer be the legal standard we have to overcome before exercising our rights to self defense in today’s increasingly tribalized world.  This is important information to consider.

•  An article analyzing whether .22 LR, .22 Magnum, .25 ACP, and 5.7x28mm are good defensive rounds. I have a couple disagreements with the article and/or conclusions. First, the article starts off talking about "mouse guns" and "micro pistols," but then includes the 5.7x28mm. All of the 5.7 pistols of which I'm aware are full size (i.e., duty sized) handguns. And, as becomes apparent from his discussion of the Fort Hood shooting, the 5.7 is in a completely different class from the other calibers discussed in the article.

    Second, the author states:

I will just pass right over the .25 ACP. Despite the compactness of some of the pistols that use it, it offers nothing the .22LR doesn’t, ballistically, and does so at greater cost, less availability and fewer options for pistol choices.

Well, the .25 ACP may not offer better ballistics but it does offer something potentially much more important: because of the cartridge design and the fact that it is centerfire, it offers more reliable ignition and operation.

• If you have a revolver for self-defense, Greg has linked to a truly excellent article from Firearm News entitled "Self-Defense with a Revolver: Fundamentals and Tips." I've printed it so I can keep it as a reference. 
• An article I found interesting was one from the Tactical Professor that tested whether a handgun with a longer barrel was more accurate at self-defense distances and easier to recover from shot-to-shot. The test was performed using revolvers of different frame sizes and barrel lengths, but of the same caliber. One of the short barreled revolvers did the best.
• An article from Massad Ayoob on the importance of being able to use your support hand to shoot and manipulate your handgun. Besides the fact that you might injure your hand (unrelated to a self-defense shooting) and have your hand/fingers in a splint, cast, or sling at the critical time, Ayood also points out:

Let’s say you want to take care of yourself and your loved ones in life-threatening emergencies. Any smart carrier is going to work on “weak-hand only” shooting (and reloading and malfunction clearing) due to the high percentage of wounded good guys in gunfights taking the hit in their dominant hand or arm.

Besides which, you might have someone grab your dominant arm in a fight. 

• Finally, check out the video from Active Self Protection, "Switched-On Concealed Carrier Wins Insane Gun Fight Against Moto Robber." Some good lessons.
