It's really more of a point shooting technique than a competition/aimed fire technique. It's for fast moving shooting at very close ranges.
Not really.
Yes.
From the article.....When your left arm is fully extended with the c-clamp technique, it doesn’t help much if someone grabs the end of your gun and tries to take it from you.
Your arm doesn't have to be fully extended. In fact, the author's arm isn't in his demo picture of the method.
One of the biggest advantages of the carbine over a pistol in close combat is the ability to muzzle punch a suspected threat OR muzzle punch in the event of a malfunction.
Muzzle punches are a terrible idea and a great way to accidentally shoot somebody.
Who is the author planning on punching with the muzzle of his loaded rifle?
For you, it might be a friend of one of your kids sneaking in to sleep off a hangover, a confused neighbor, or some other situation where a muzzle punch is a MUCH better instinctive reaction to a bump in the night than shooting first.
hmmmmm.......
If you train yourself to always reach your support hand out to full extension and use the c-clamp grip, sooner or later, you’re either going to grab a handful of hurt (in the form of a burn or a hole) or you’re going to run the gun slower out of respect for the potential of grabbing a handful of hurt.
On an SBR that's not the result of a C-clamp grip, it's the result of terrible weapon handling.
And then there's a bunch of blather about push-pull. You wanna talk about wearing yourself out? Run around doing the push-pull stuff for just a bit and see what happens.
