Weekend Knowledge Dump- January 24, 2025

Knowledge to make your life better. If you have some free time, check out some of these links this weekend.

 

Shoot While Moving vs. Move Then Shoot

The longer I stay in this game, the more I’m in favor of either moving or shooting…not doing both at the same time.

 

 

Red Zone Knife Defense Digital Download Video

If you are looking for a system to teach you how to defend against a knife attack, I’ve never seen anything better than this one. I’m excited to see that Jerry has put his system out on downloadable video for all of you to watch.
 
I hate watching technique videos and I’m still going to watch this one. You should too.
 
 
 
 

Why a .22 LR Pocket Gun Should Not Be Underestimated [2025 Update]

Important concepts to consider.

 

 

A Common Weakness: One-Handed Shooting

Tune up your one-handed shooting skills.  You should also consider this  information when deciding the contents of your practice sessions. 

 

 

Why Some Handguns Are Harder to Master

Information you should consider when choosing a defensive firearm.

 

 

[Study] Home Defense Overpenetration: Shotgun, Handgun, Rifle

There is a lot of very valuable ballistic testing data in this article.  The author fired rounds through a block of ballistic gelatin.  He then placed a simulated interior wall and a simulated exterior wall behind the gelatin block.  He tracked how much penetration some common defensive rounds produced after going through the gel block.

I would not automatically dismiss any of the rounds he marks as a failure for overpenetration.  Just because a round penetrates those barriers does not mean that it is moving fast enough to harm someone on the other side.  A lot of the bullet’s energy is used up penetrating the barriers and it may not have the velocity to even penetrate skin on the other side.

 

 

50 things I know

A worthwhile read.

The History and Future of the Smith & Wesson Internal Lock

Smith and Wesson introduced several new revolvers without locks at this year’s SHOT show.  Do you know about the history of their locks?  I learned a lot of facts I didn’t previously know while reading this article.  If you are a S&W revolver fan, you’ll enjoy this long form article.

 

 

Six Reasons the Exodus of Police Officers Is Worse Than You Think

Take a look at the factors identified in the article and ask yourself these questions:
 
Are these issues going to become better or worse in the next decade?
 
How do you think the changing face of policing is going to affect your individual personal safety?
 
What are you doing to mitigate the predictable safety consequences of de-policing?
 
 
 

Which Guns Did Doc Holliday Really Use

Studying the Links Between White Supremacist Terrorists and School Shooters

The author discusses how white supremacist mass shootings differ greatly from Islamic Jihadi mass killings and postulates that the white supremacist attacks might be more closely compared to school shooters.

“Let’s remember that terrorism will always be a moving target. And so we can never afford to embrace a one-size-fits-all solution to fighting it.”

Along similar lines, check out Sam Harris’ article No Ordinary Violence.  It describes differing motivations offenders possess and discusses why we shouldn’t consider all killer the same.

Have Gun — Can Still Lose

Firearms training legend Ken Hackathorn is retired now and doesn’t write too many articles.  You would be wise to pay attention when you see his byline.  On the topic of the old timers in the firearms training industry, you might want to watch the fourth and final installment of INSIDE STORY, Episode 4, Part 4: The OG Gathering.

Concealed Carry at the Gym: Things to Consider

I carry a pistol in a fanny pack every time I go to the gym.  A long time ago, I once had to draw the gun to defend myself against three Ohio State University football players (one of whom I had previously arrested) who attacked me when I was working out.  The entire incident was masterfully swept under the rug by both my police administration and the university.  Justice was not served on that day, but I learned an important lesson that I had to be prepared to take care of myself because my bosses at the police department certainly wouldn’t take care of me.
