Of course they flex, but I wasn't expecting that much wooble.


Sorry if dupe,

Lots of ejection issues.

FTE - wtf, does that gun not have an ejector installed?

Thats a lot of flex, I'm guessing would be much less when held in hand as we aren't quite a rigid as a ransom rest. But still.

I cannot believe the slide lock moves that much during firing.

Do you mean the take down tabs?
That is what caught my eye, as well as the ejection issues.

Obviously no ejector. I'm not sure why they did that.

I agree that frame flex would be different (less concentrated to small areas) when hand-held.

I missed that the first time.  Since you folks called attention to it, I was amazed at how much movement was going on with the take down tab.

It may well have had an ejector installed. IIRC, and it's been a LONG time ago, when Glocks were first coming into the country, I recall reading in the gun rags that testers were having LOTS of trouble getting Glocks to run in Ransom Rest testing. If they weren't clamped in the rest firm enough, they moved around and malfed. If they were clamped in too firmly, the frame got squeezed and the gun malfed. I think I remember reading about ejection issues, too. Again, IIRC, the supposition was that the poly frame couldn't flex in a rest the same as in a hand and that this uneven flexing when clamped was causing the gun to run improperly and malf. Again, I could be remembering wrong since this was a long time ago, but that's the way I remember it.

"limp wristing" is a significant problem for polymer guns, resulting in a lot of case ejection failures.  So if the clamp wasn't firm enough, it may have resulted in the same outcome as a limp wrist grip.

Pretty cool, reminds me of that AK slo-mo video

That first shot, I think the dust cover actually smacks the under side of the barrel***ETA***I guess it was just the guide rod

Damn I would never believe it flexes that much, thanks for sharing that OP

From the author:

"It's fired in a Ransom Rest ... it takes a while to get it adjusted correctly to allow for proper forward cycyling. The purpose of the test was only to measure the rearward velocity vs. amount of magazine "fullness" so we set up a constant resistance to the slide moving rearward"

Yes, I read that too.

It doesn't however say anything about the gun having an ejector installed or no.

I don't need to explain limpwristing to you guys, but in the video you can see that slide fully cycling rearwards and still no ejection. When limpwristing, the slide doesn't always fully travel rearwards resulting most of the time in FTE-FTE but I don't believe this is the case here, I believe that pistol has got no ejector in it.
If it indeed did have one, then

Read through the comments, it has an ejector.  The rest is just not adjusted correctly to allow the gun to feed.

Nowhere in the comment section and eventhough directly asked, the OP of that video 'brass fetcher' answers the question whether or not the gun had an ejector in it.

'was your ejector extractor broken?' Was the direct answer, addressed by a 'its fired in a ransom rest, it takes a while to get it fully adjusted to allow for proper forward cycle..'

Am I missing something here? How can you be sure?
Not arguing for the sake of it, just trying to get to the bottom of this.
Its simple physics, if that slide  cycles all the way rearwards like this one does, then the shell case WILL come in direct contact with the ejector, given the extractor is functioning properly.

The shellcases in the video, are not coming in contact with anything.

There are some high speed videos out there of heavy bolt action rifles firing, if you think that only polymer stuff flexes.
