Reaper Tips: 4 Precision Rifle Shooting Errors


Are you making any of these precision rifle shooting errors?



The Problem With Remaining Silent


Many gun gurus will advise you to “never talk to the police” after a defensive shooting.  I don’t agree.  While staying silent is certainly better than providing too much specific information, the best outcome for the defendant will combine the strategies of not speaking freely or specifically, but providing a certain amount of limited information to the police.  Read the article and think about it this way:  “If I have information that will obviously HELP my case, why should I hide that from the police?”

If you are confused about the issue, I would suggest you read the books The Law of Self Defense by Andrew Branca and/or  Deadly Force by Massad Ayoob.


For a More Creative Brain, Travel


Third world travel has certainly been the single most transformative experience in my life.  Science is now figuring out why:

“Foreign experiences increase both cognitive flexibility and depth and integrativeness of thought, the ability to make deep connections between disparate forms,”

Anthony Bourdain’s 3 Best Tips For Eating Great When Traveling Abroad


Many of my friends who haven’t traveled much are scared to death to eat the local food in another country.  Instead, they only eat  at American-owned restaurants like Pizza Hut, Starbucks, and McDonalds in the misguided attempt to avoid food-borne illness.  Not only are those folks missing out on some amazing local food, they are actually more likely to get sick.  Foreign versions of American chain restaurants catering to tourists have some of the worst food handling practices on the planet.  Stay away from them!  In this article, Anthony Bourdain explains how to find a good local restaurant in another country.

“Technology Hand” Is Destroying Your Upper Body Strength


I’ve never heard of “tech hand” before, but it seems to be a likely consequence of our constant use of electronic devices. Try the exercises in the short video. I bet the hand you use to operate your computer mouse will be tighter than your other hand.


How To Clear a Double Feed


All serious defensive shooters should be able to reflexively clear semi-automatic pistol malfunctions. It is a skill set that I seldom see mastered in my less experienced students. This article explains a basic technique to clear one of the more difficult malfunctions. The article suggests locking the slide back as the first step. I do that, but it may not be necessary in all guns. If you can adequately grasp the magazine and rip it out of the gun you may be able to omit this step.

Double feeds as described by the article are difficult to spontaneously simulate in practice using dummy rounds. Those will generally chamber and extract properly, so you’ll likely never see a double feed. Instead, mix up some empty cases in with your magazine’s live rounds. Some of those will chamber and some won’t. You’ll get a good chance to practice the clearance method the author advocates.




A Few Reasons I Like The Kalashnikov Better Than The AR-15


Some often unconsidered benefits that the AK-47 has over the AR-15. I like both weapons systems. Although the AK has some undeniable advantages in certain circumstances, I think the average shooter is better off with an AR-15 if he was only buying one defensive rifle.


Since we are talking about AK-47 rifles, here is some more information for you. Be careful which safety lever you install in your semi-auto AK.




Why the police shouldn’t use Glocks


Last week the LA Times posted an opinion piece about why cops shouldn’t carry Glocks.  I think the article is ridiculous.  So does Claude Werner and Jeff Gonzales.


Skull-Stomping Sacred Cows: Weakness is Cowardice.


John Mosby knocks it out of the park again:

“We spend a lot of time talking about the practical values and importance of training. Training is far more than that though. It’s MORE important than that. Training is about introspection. It’s about digging deep inside yourself, and finding the spirit of self-sacrifice within yourself. It’s about finding the part of you that is willing to give anything to protect the tribe. It’s not easy to find, despite the blustering machismo of too many mouth-breathing assholes. It is discovered at the moment of failure, in ANY training evolution, when you nut up and say, “fuck it, I’m not done yet!” and you drive on until you surpass failure.




Are “too many” criminals being killed by the police.  This article examines the math involved and shows that the police actually exercise a tremendous amount of restraint in most cases.

  • Only 13% of the situations in which officers are legally justified in using lethal force results in a citizen death
  • Only 8% of the situations in which officers were legally justified in using lethal force against an African-American male results in a death
  • While African-American men make up 44.3% of assailants against the police, they only make up 26.3% of the deaths from legal interventions

2 Comments For This Post I'd Love to Hear Yours!

    I posted this on bearingarms.com in response to the Bob Owens article on Glocks and cops:

    Mr. Owens, in reading your blog and this article, I noticed that you are a proud Gunsite graduate, and use same to lend authority and credibility to your pontifications on the subject of defensive handguns and shooting – so, I got to wondering which pistol you used for Gunsite 250?


    Oh, a Walther PPQ – ummmm, that looks a lot like one of those “unforgiving” polymer-frame, striker-fired pistols with a short trigger pull and no external safeties…

    Wonder what the trigger’s like on that pistol?

    “Quick Defense Trigger: Smooth, light 5.6 lb trigger pull for all shots. Short .4″ trigger travel and .1″ trigger reset for fast, accurate second shots. Facilitates double-taps. Superb trigger feel aids accuracy.”

    By Jove, that sounds an awful lot like…a Glock or a S&W M&P. But, since it’s a *Walther*, it must be OK…


    So, how did you do at Gunsite with your “NotAGlock” Walther PPQ?

    “Yes, I “died” three times at Gunsite.

    In two runs on different indoor simulators I got tunnel vision. I cleared the rooms with deliberate intent, focusing so closely on every interior corner and angle that I simply failed to notice solitary bad guys standing outside the windows as I passed by.

    My third “death” was simply mortifying. I successfully cleared a room, and then encountered a target almost right on top of me in the narrow hallway beyond. I pointed, instead of looking at the front sight, and yanked the trigger instead of pressing it. I missed twice at five feet.”

    Golly gee willikers, you went to some of the best defensive handgun training in the world, and during a run in the Gunsite Funhouse – still regarded as one of the premier facilities for police gunfight and CQB/house-clearing training – you STILL ganked a couple of close-range shots with “a polymer-frame, striker-fired pistol with a short trigger pull and no external safeties.”

    Guess “the brutal reality that short trigger pulls and natural human reflexes are a deadly combination” worked out somewhat differently for you…

    If only you’d been using one of those “DA/SA handguns like the Sig Sauer “P”-series, the Beretta 9 series and PX4 series, CZs, Smith & Wesson’s metal-frame semis,Ruger’s SR series, etc.” “with much longer double-action triggers that are just as easy to fire deliberately but that are much harder to fire accidentally,” as the founder of Gunsite, the late Col. Jeff Cooper advocated – oh wait, here’s what Col. Cooper ACTUALLY said about DA/SA pistols:

    October 1973–“Double action in an auto pistol seems to me an ingenious solution to a non-existent problem.”

    “In reflecting upon a recent all-cop pistol session we conducted over in California, it is apparent once again that cops, as a group, are pretty hard to train. Those who are stuck with the crunchenticker – and these are many – will persist with the slow-crunch technique in spite of all advice to the contrary. This system is almost universal in the law enforcement establishment. If it is done accurately it is too slow. If it is done rapidly it is inaccurate. It is possible that I am paying too much attention to unrealistically high levels of performance, which are really not necessary in gun fighting. Still, I like to see people do as well as they can. It is bothersome to see them make no effort to do so.

    There has never been much question about it, and it is indisputable after decades of observation that the single-action self-loading pistol – the Colt 1911 and its clones – is the easiest, heavy-duty sidearm with which to hit. The crunchenticker is the most difficult, and the Glock is somewhere in the middle. Shooting a Glock is simply shooting a single-action self-loader with no safety and a very poor trigger. If real excellence is not the objective, this is a satisfactory system to employ.”


    Perhaps Buz Mills should consider revoking your Gunsite 250 certificate for “blatant public hypocrisy unbecoming of a national gun-rights advocate,” or at least requiring you to repeat the course with a Beretta or SIG DA/SA pistol “with much longer double-action triggers that are just as easy to fire deliberately but that are much harder to fire accidentally” – and you yourself might want to read Matthew 7:1-5 before attempting to pander to low-information readers again…

    This is my response to a later rebuttal elsewhere on Facebook:

    I’m glad that Bob Owens got to graduate from Gunsite, and I greatly enjoyed the articles he wrote about his experience when I first read them.

    I’m OK with the fact that he used what many would consider a “gamer gun,” his 5″ longslide Walther PPQ, even though he admits that “The Kahr CM9 is my current every-day carry gun.” (http://bearingarms.com/mine-nine/2/) He’s not alone in training with a range gun and carrying a subcompact pocket pistol, although I’d say it’s a shame to throw away 5 days and 1000’s of dollars and rounds worth of top-notch training and “muscle memory” by not carrying the same gun that he trained with(or at least stick with the same operating system, by carrying a Walther PPS).

    I like and own several of the DA pistols Bob referenced in this latest post, and I actually agree with him that they’re not that hard to shoot, once you learn how. I just wish he would have argued FOR DA pistols based on their own merits, instead of AGAINST short-trigger, no-external-safety pistols like the one he himself used at Gunsite.

    I don’t even have a problem with the fact that he completely missed a target under pressure at extremely close range – I’ve done the same in IDPA matches, and as long as we didn’t harm or endanger ourselves or a fellow shooter, honestly acknowledge our own fault, and learn from the experience, it’s OK(all of which Bob Owens did, to his credit: http://townhall.com/tipsheet/townhallmagazine/2014/11/13/gunfighter-school-n1914586).

    However, what beggars his credibility and my credulity, is less than a year later, while speaking in a national forum as a national advocate and authority on gun rights and gun ownership, blithely dismissing the same kind of human fault and error as being an unavoidable part of human nature, and instead assigning blame to the inanimate tool. It’s as if Bob Owens unilaterally decided that cops and other folks who carry Glocks and similar pistols can’t reasonably be expected to learn and adhere to Cooper’s Rules of Gunhandling(as he was personally taught at Gunsite itself mere months ago), because training is “utterly irrelevant,” when “humans are gonna be human,” and instead they need guns designed to take more of the burden of safety out of our frail, fallible, merely-human hands. I can’t imagine that Col. Cooper would have tolerated that for a second, as staunch an advocate of personal responsibility and training as he was, and I doubt that the current staff of Gunsite would feel any differently.

    I have to wonder, why the change? Did Bob Owens have an epiphany at Gunsite, or shortly after, that suddenly made him realize why short-trigger, no-external-safety pistols like Glocks and S&W M&Ps(AND his Walther PPQ, AND the Springfield XD9 he ALSO used to own) are such a bad idea? Did Bob, or a fellow student, have an AD under circumstances similar to the cops he cited in his article? Did Bob somehow come to the realization that he wouldn’t have been “killed” in the Gunsite Funhouse if his pistol had had a long, heavy double-action trigger like his Kahr CM9(which he DIDN’T shoot at Gunsite)?

    If so, why didn’t he say so in his article? Space limitations aside, surely he could have squeezed in a simple sentence or two about how his personal experience owning short-trigger, no-manual-safety pistols and shooting same under stress at Gunsite made him realize how unforgivingly dangerous they are?

    At least he could have covered himself by acknowledging that such pistols are indeed safe(r) in the hands of trained, conscientious handlers – that would have been merely “elitist,” and wouldn’t have offended thousands of Glock owners who ARE trained and conscientious(or at least regard themselves as such).

    As it is, the tone of his L.A. Times op-ed and his follow-up article strongly suggests to me that Bob Owens decided to pander to the current popular narrative that “cops shoot too many [non-white]people,” and chose to lay the blame at the feet of the guns used(which are strikingly similar to the ones he himself admits to owning and training with), because that line of reasoning was easier to sell to the Times’ editors and readership…
