March 4, 2017--A Quick Run Around the Web

Although the inmate screws up the attack at the end, this actually demonstrates how to get the garrotte around someone's neck. I would point out that a towel may not be the best garrotte--British commandos, during WWII, used garrottes made of barbed wire. More information on the incident described above can be found at the Daily Mail.

Many shooters hold their fingers this way [trigger finger alongside the trigger guard] when not firing.  They believe that since the finger is not on the trigger, an accidental discharge won’t occur.  In general, they are correct.  But most shooters don’t know that certain situations can cause an involuntary hand clenching.  The tightening of the hand causes a contraction of all of the fingers with a force up to 30 lbs. (the Glock trigger pull weight is around 6 lbs.) and cannot be consciously controlled.
He goes on to explain that:
The three most commonly identified causes of involuntary hand clenching have been extensively studied.  They are as follows:
    1) Postural Imbalance.  When the shooter loses balance or trips, his hands will clench.
      2) Startle Effect.  When the shooter is under stress and surprised, there will often be a hand clench.
        3) Interlimb Interaction.  Under stress, when the non gun hand closes violently, the gun hand will clench,  spontaneously duplicating the actions of the non-gun hand.
        He discusses the is much more detail, so be sure to read his whole article.
        The obvious solution is to rest the finger higher, along the frame or bottom edge of the slide. He offers his two favorite options: First, "[t]he one I use and teach is to place the trigger finger as high as possible on the slide without disturbing the grip." Second is that taught by Massad Ayoob: "placing the finger fairly high on the frame with the trigger finger bent or curled.  The bent position causes the finger to curl onto the frame if the hands are clenched.  This position also gives the shooter a little more strength to resist a gun grab attempt."
        Some firearms offer some natural indexing points to let you know if your finger is properly located. For instance, Ellifritz relates that "feeling the bottom edge of the ejector port let’s me know my finger is in the right place.  On Glock handguns, the slide lock lever makes a good indicator for the Ayoob position."
        That is one of the features I thought particularly well thought out on Remington's R51 is that there were serrations just above and forward of the trigger (see photo above) to use as an index for resting your finger.

        Other Stuff:
               The skulls, which are described in a new paper in the journal Science, were discovered in Lingjing, China in 2007 and 2014 and are between 100,000 and 130,000 years old. Researchers are calling them “a morphological mosaic” because of a collage of characteristics.
                 They’ve got Neanderthals’ ear canals, eastern Eurasian humans’ low and flat brainpans, and similarities to early modern Old World humans, too.
                   The skulls are distinctive enough that they seem to belong to an entirely different species—one that’s neither human nor Neanderthal, but that shares characteristics of both. One explanation is that they’re Denisovans, a recently discovered ancient human cousin thought to have interbred with both humans and Neanderthals. ... 


            1. Re: "How to Glue Anything to Anything Else"

              Popular Mechanics omits my two favorite glues: J-B Weld two-part 24-hour epoxy and Shoe GOO glue. I've used J-B Weld to make numerous automotive repairs and repair an incredible number of other things. Plus, it can be filed, sanded and drilled after it cures. Shoe GOO is excellent for repairing shoes, both gluing them back together and building up worn shoe soles. I've also used it to glue other porous or semi-porous materials requiring some flexibility.

              1. Thanks. I'll have to try the Shoe GOO. I've noticed with some of my athletic shoes that the soles will start to peel back in places, although the rest of the shoe is in good shape. I've tried to make repairs with a shoe glue, but it didn't hold up very well.

              2. When gluing shoes with Shoe GOO, first make sure the surfaces to be glued have been cleaned to remove dust and any oil. Generously apply the Sho GOO (use a finger, the glue rubs off afterward), and somehow clamp (a real clamp, rubber bands, etc.) the pieces together overnight.
