Gen 4 Glock 17 update

General Firearms Handguns - Semi Auto
1

Quick update;

the G17 Gen 4 I got for the show has ran great BUT I locked the slide to the rear in the box for about a week

My guess is that is a must

My bro Hackathorn just did a class and two Gen 4 G17’s had mega problems - ammo was PMC ball

This prompted him to call his Glock POC and fill him in - the guy said a fix ‘might’ be in the works

This guy also said Glock WILL NOT stop producing the gen 3 guns

Also ref a Vickers Tactical/Tangodown mag catch for the Gen 4 Glocks - we are going to look hard at it; we think it may be enough of an improvement to do it

That’s all for now - almost done filming this seasons Tactical Arms so back to work

Cheers

Thank you Mr. Vickers.

I had been wondering about the Gen III production status.

Thanks for the update!

Thanks for the update Larry! It’s good to hear they’re going to keep going with the Gen3s.

5

Can you tell what kind of problems the two Gen 4 G17’s had in Mr. Hackathorn’s class?

6

Again, much appreciation for your input on the subject. I’m glad to hear GLOCK may work on a “fix” for the gen4 9mms. Also good to know that they are keeping the Gen 3s!

Thanks for the update and please keep them coming.

Thanks for the info Larry!

I will echo, thanks for the input.

Good info. I get my Gen4 17 today, and I will lock the slide for a week as well.

11

Good to know. I still want to pick up a Gen4 to put through it’s paces but I’m glad to hear that the Gen3 will be staying around (at least for the time being).

12

what is the purpose of locking the slide back for a week?

13

The people who are having problems, are they having them right out of the box, or after so many rounds? I have a low round count out of mine (400) and haven’t had any problems yet.

Thanks

To reduce the strength (tension) on the spring.

From reading the other posts about the GEN 4 9mm’s, it appears to be early on when the recoil spring is the strongest.

In the class that Ken taught, the shooters could have been limp wristing the guns and might have nothing to do with the springs.

Ken is stopping in our shop today so I will see if I can get any more details from him.

I had my problems all with UMC ammo in the first 300 rds or so. Now it runs everything I feed it perfectly. Wish I had some Wolf to run through it. I have taken it to one class and it ran perfectly for me and a couple other guys on this forum.

17

that’s what I suspected but doesn’t that kind of go against modern theory of spring fatigue?

over and over again, I have been assured that leaving a mag loaded will not fatigue a spring but it is only the cycles of operation that can do that.

what am I not getting? :confused:

18

Using a mag (cycling) and keeping a mag loaded and letting it sit (are two different things). Compressing the spring (by locking the slide back) will cause it to take a “set” are reduce its power.

This was my first thought as well.

But would not “using the mag (cycling)” equate to firing the weapon? This would be compressing and uncompressing the sping?

“Compressing the spring (by locking the slide back)” would equate to storing a loaded magazine, a static condition, no?

20

Firing the weapon does cycle it and DOES wear down the spring. This is also likely causing you to deal with malfunctions. So by storing the slide to the rear, you are most likely causing the spring to take a set faster.

Make sense?
