Forget Fundamental…Call them ESSENTIAL!


Dave is absolutely correct:

“To me, a person becomes a combative firearms instructor because they want to save lives… to help good guys and gals prevail when their life or the lives of loved ones are on the line. It’s about offering solutions to real problems, not imparting personal doctrine at the cost of all else.

Guide to Budget Ammo


I’m not worried about steel cased ammunition in general, but I do stay away from a few brands.  I don’t shoot Hornady’s steel case .223 ammo after I witnessed a squib load blow up one of my police department’s M-16 rifles.  I also refuse to use Tula ammunition (in any caliber).  I’ve had two factory armorer instructors (for two different handgun companies) tell me that Tula ammo is responsible for more gun ka-booms than any other brand.

Adversarial Attraction: the Predator’s Optic


What do criminals look for when they choose a victim?

“The top cues to vulnerability were: Walk/gait – walking with confidence versus walking like a soft target. Gender – females appear as softer targets than males. Body type – In good physical shape (could put up more of a fight) versus heavy set or slow (less physically challenging). Fitness level – Greater probability of fighting back versus unable to defend self. Attention to surroundings versus Not paying attention; Appears to be cautious versus appears to be clueless.

In distilling the above, there are three overarching Soft Target Indicators that command a predator’s attention at first glance. These are; if you appear to be:

  1. Weak – physically, mentally or otherwise
  2. Unaware – distracted (lack of situational awareness) clearly not paying attention to your immediate surroundings – including them watching you
  3. Alone – easily accessible, vulnerable, exposed, or some combination thereof

You can appear to be any one of these or even any two of these, but all three combined – weak, unaware and alone –well, that’s the predator’s jackpot – three sevens in Vegas!”


You also want to be aware of anyone who is maneuvering to increase your “Scale of Injury.”
