Author Topic: Chambering a Glock with inertia (vid) (Read 1150 times)

9Shooter · « **on:** November 16, 2009, 01:10:30 PM »

After watching the full speed version initially I was left thinking 'what just happened here?' Watch the slo-mo just after and you can see the guy uses the reward inertia of the slide to rack a round with one hand as he starts the CoF. According the the site I found it at, the pistol has not been modified, but I find that hard to believe.

Try it with snap caps, just to see if you could do it.

Good freakin luck!! I can do it with my STI that has a 10lb spring in it, but I can barely get my Glock to come out of battery. Maybe I need to try it on the extended length slide models.

I'm quite positive he has a low power recoil spring and lite target loads!

No other way to make that happen?

At first I thought he was snaggin his shirt to rack the slide, but in the slow versions you see it's just rear kinetic energy.

Target guns set up for target shooting, you can try new things.

But hey a cool Video none the less, Thanks Todd

Really light spring I'm guessing, some of those race guns feel like the slide would just come off if normal ammo was shot through it.

I think you are right as it took a few rounds to take down the last target. On the other hand why would someone do this? I thought the whole point was to get good at how you plan on shooting. Who is going to walk around with a week spring and target loads everyday?

tgibson · « **Reply #6 on:** November 17, 2009, 07:18:05 AM »

Just because you are running a light spring doesn't mean you have to run reduced loads. I have run CCI Gold Dot rounds through my 3 gun pistol that has an 11lb spring in it. If the ONLY thing I was going to run through that gun was the CCI rounds, I'd probably up the spring weight, but it runs just fine with the spring it has in it now.
As far as getting good with what you carry, I really don't think it matters what you are shooting as long as you are putting rounds down range. Unless a person is just physically unable to hang on to a .45, you could go out and practice with a .22 or a gas blowback airsoft gun and get all the fundamentals down pretty good. It takes a little longer for a .45 to come back onto target, but if you know what to look for, you can still shoot it well.

Nope, that's what tactical training classes are for.

IDPA's "main goal is to test the skill and ability of the individual, not
equipment or gamesmanship."

Shooting matches like IDPA help refine one's ability to shoot with unconcious competence therefore allowing you to focus on the tactics rather than gun/holster manipulation.

As to the topic at hand, it's fun to watch him, and as to practicallity, well if your weak hand was incapacitated and you had to reload your gun to stay in the fight, it does work.

There was a followup to the post I read that had formulas calculating the force it would take to make this work.

We can figure out how fast a Glock has to be traveling in order for the slide to rack when the Glock comes to a halt. We can do this through conservation of energy. The Glock 19 spring takes about 15 lb. or 67 Newtons to move the spring the 3.5cm it needs. Given that the energy of a spring is 1/2 Fx, that give us 0.5 * 67N * 0.035m or 1.17 Joules. To generate enough kinetic energy, the 350g Glock slide would have to move at 2.6 m/s. The human body is certainly capable of generating this kind of speed, but I’m a bit more skeptical one could stop the movement of the gun quickly enough. From a matter of force, it would take an acceleration (using F=ma) of 191 m/s^2, or about 19.5x the force of gravity. That sounds like a lot of acceleration, but it’s not beyond human capability.

And there you have it...

That is assuming that there is no friction between the slide and the pistol.

I tried on a stock G19 with no mag installed and I could barely get the slide to move.

tgibson · « **Reply #12 on:** November 17, 2009, 09:35:08 PM »

I'm not saying it can't be done but last night I put the gun in my strong hand holding it around the barrel and just slammed it into my other hand to see if I could get it to lock back with just a sudden stop....no dice. I guess it has to be a combination of a sudden stop immediately foLlowed by a sudden start. Tried it again last night and could get it started but not even close to picking up another round. FWIW.

If I didn't know better after watching that a lot, I might think he is canting the gun inward slightly and catching the rear sight on his shirt along with a very light recoil spring to achieve his " Ninjaness" of a load. Look at his chest just past the load and see what goes. I dunno could be.

e11charlie · « **Reply #14 on:** November 18, 2009, 07:13:32 AM »

I think you may be right pops. From further looking the slide doesnt seem to actually move to the rear until is hand stroke moves forward. This could be due to him catching it on his shirt. I still do not see how even with a soft spring how he has the force to throw the slide like that. But then again maybe he is a gun god sent to earth to test the the faithful.

luvmy45 · « **Reply #15 on:** November 18, 2009, 08:27:08 AM »

The slide not moving till his hand stops and moves forward would be correct. It's the action of stopping the hand and jamming it forward that is racking the slide. Simliar to cracking a whip, with the wrist, it's that last little whip that does it.

Ok neat video, but....

I just spent the last three hours attempting the maneuver with various handguns. I started with a Glock 17 (no success) and decided that the tiny slide did not have enough mass to accomplish the task (overcome the pressure from the return spring). I moved on to my Sig P220 (bit more mass) and still had no success. My elbow was getting a little sore by then but I decided to try the old Colt 1911. Predictably I had no success with it either. Now my morning is shot and I have a sore elbow. I guess I'll just watch the video again and see if I missed anything. I have a couple old worn out springs that I might put in and see if that helps. Maybe I can waste my afternoon too.

Well maybe some of them have strained there wrists too much to try this one hand glock thing

Depends on the lenght of stroke a guy gets to practice with.

Don't know about a glock...never tried.
Easily done with a highpoint...sometimes it will even slam fire.
