Head Buttin Time! How to Head-butt A Bad Guy Real Good


Some tips about using head butts effectively.  The best advice I ever got about headbutts came from Jujitsu legend Relson Gracie at a ground fighting seminar I was attending.  Relson is known for teaching headbutts for self defense.  Relson’s advice was “When you head butt somebody, you are the devil.  You must hit him with the place on your head where your devil horns come out.”  That’s a strong part of the skull and tends to hurt a little less than hitting the guy with their forehead.



Just The Tip: Surefire X300U Edition


Some slick modifications to make your Surefire X300U better fit your guns and your hand.  The X300U is the best pistol light on the market right now and the only weapon mounted pistol light I use.  I use the DG switch with mine.

A 90-page book that looks at all the published research on police ambushes, how to avoid them and how to survive if your avoidance tactics are ineffective.  Opens to PDF.

If you are into police related academic research, here is a study about how often suspects suffer brain injuries from falls after they’ve been Tased.  The answer?  16 cases out of more than 3 million total uses studied.



Deadly Calls and Fatal Encounters

FireShot Screen Capture #032 - 'National Law Enforcement Officers Memorial Fund_ Deadly Calls and Fatal Encounters' - www_nleomf_org_programs_cops_cop

One more piece of cop research for you this week.  This is a very compelling study looking at how cops get killed when responding to calls for service (as opposed to self initiated field activity).

Racism and Violence in America


This is an amazing conversation between Sam Harris and Glen Loury about the state of race relations in our country.  It’s more than two hours long, but well worth the time.  I learned quite a bit and highly recommend it.

SHTF Armorer: Magazine Maintenance – Part 1


Lots of people think about gun maintenance, but fewer people understand that magazines need some preventative maintenance as well.  Read Part 2 as well.





Good close range rifle shooting drills here.  I like to use these as diagnostics.  They are good drills to use when comparing different rifles or the effects of different shooting stance modifications.  They easily show which of your changing variables makes a difference in controlling the rifle.



How To Be An Expert: 8 Proven Secrets To Superior Skill


Quality research to help you gain more expertise in any enterprise.



You’re Too Stupid For This Conversation You Insist On Having


“We have news media, politicians, gun control cultists and pro-criminal “peace” activists all pushing for a “national conversation” on the use of force by concealed carriers, homeowners, and law enforcement officers. I’m not aware of even a single one of these blowhards having the first bit of professional training that would equip them to intelligently discuss the merits of a taser over a baton over a chemical spray over a firearm in a given situation, much less qualify them to pass laws and policies determining their use.But as insane as it may be, people are listening to these people, simply because they’re emphatic in their ignorance.

Until we stop accepting the foolish notion that uneducated opinions matter more than the experiences and educations of experts, we’re going to see things just keep getting worse, not better.”


A message to instructors…

Terrifying video shows man mercilessly punching a woman in broad daylight in what police say was a random attack


Perception is reality in terms of criminal psychology. Watch the video of this seemingly random attack. A man chased down a woman and punched her numerous times. The only thing he said during the attack was “Say you’re sorry.”

Clearly, the attacker felt slighted. It doesn’t matter if YOU didn’t mean to insult someone. The only thing that matters is how THE CRIMINAL perceives what you are saying.

There was an interesting study done in California a while back. It was reported in Michael Ghiglieri’s excellent book titled The Dark Side of Man. The researcher, David Luckenbill, studied all of the convicted murderers in a California county over a 10-year period and asked them why they killed their victims. You would expect to see a variety of responses. You would be wrong. Every death row inmate interviewed listed one of only two reasons for killing….

– 34% said they killed because the victim challenged the killer’s authority

– 66% said they killed because the victim insulted them in some way

Like I said, the truth doesn’t really matter here. What matters is the criminal’s perception. If he perceives a challenge or an insult you are far more likely to be hurt and/or killed.



Sharpshooting North & South: The Genesis Of Sniping


Very cool article about the weapons and standards used by Civil War era snipers.  One requirement was 10 consecutive shots into a five inch circle at 200 yards from standing position.  That’s pretty good shooting!
