also note worthy  on the tungsten guide rod (which I bought new) I noticed what I would describe as chatter marks maybe galling would be a better description?

These seems to happen on other tungsten guide rods as well...owned lone wolf and glockmiester.   Maybe they are all outsourced to the same place? who knows?

Anyway, while I think it's unlikely these marks would degrade reliability...they happened inside of 100-200rds ...so what do they look like to a serious shooter at 5000-1000rds? Plus if I'm paying $50+ for a guide rod...it just would bother me that it's doing it.

Still I like the idea of the tungsten GR, but for me, it just doesn't meet my expectations.

The_Shadow

before this test I bought the wolff round, 20lb 22lb and 24lb ...for some reason the lighter springs were longer and heavier springs were shorter.  Doesn't seem to make sense to me  but that meant the heavier springs didn't bind up and the lighter ones did.

Conversely the 24ISM (bought and tried before this video) was the longest of the flat springs and seemed to bind up a little bit.  Probably why ISM no longer makes it.

From what I know ISM (small father son shop) redesigned the spring with a new hybrid steel which is what is now used in the 22lb springs being put out.   I know the Brass stacker felt a little bit stiffer than the glockstore tungsten guide rod.  My guess is because GS doesn't sell as many tungstens and thus that 22lb was old inventory...older style ISM 22lb. 

Basically the new hybrid ISM 22lb springs were quoted to me as being more like 23.5lbs if measured by the old standard but they just stayed with calling it 22lb.

Bottom line for me is...

1. I saw no added value with the tungsten  plus for the price that brass stacker charges ($22 shipped) I can get two of them for less than the price of the tungsten by glock store  ($50+5 shipping).

2. I did not like how the spring was riding the thinner lone wolf guide rod vs the thicker brass stacker guide rod. Plus the lone wolf actually costs more.

3. I saw no difference between the 22lb and 24lb wolff.

4. I've got about 1000rds on the 24# wolff now and probably after 400-500rds it started to lose some of it's power/memory.  I have about 500rds on the brass stacker ISM and there seems to be no loss of power/spring memory.

5. all that said I have narrowed it down to testing the 22lb brass stacker vs the 24# wolff for part 2 of the video/test - I will use brand new springs in part 2 so it's apples to apples.

6. Even if your a stocker (swear by stock glock) the evidence so far suggests there is no harm in using at least the 22lb ISM setup and only benefits as it would a. recoil less. b. beat up the gun less. c. likely make you more accurate as you wouldn't have a flinch or as much of a flinch... d. reduce ES (extreme spread) e. in my experience gives a slight increase in velocity.

I used probably the weakest 357sig out there...to show that even a 24# wolff spring would cycle it.  What surprised me was that a 17lb didn't kick out the brass any further than the 24# round spring.

Why it's so surprising....is because the difference in how hard it is to rack the slide with a 17lb flat spring vs a 24# round spring (wolff) is night and day!


anyway I'm looking forward to doing part two. I really want to see if there is a difference in accuracy or point of impact shift.

also want to see the reliability. The more I played with the 24 round spring vs 22lb ism flat  and the more I watched the videos the round spring seems to slow down the slide to much and I feel it could lead to function issues. After all the gun was designed with a flat spring. But that is why I test stuff ...to be sure.

couldn't agree more

I heard Iceland was trying to import & adopt 10mm so they could become a Nuclear power! 

technically with the SLB barrels cut like this they are slightly out of battery???

So shouldn't that be a safety concern??? if not a timing issue with slide unlocking too soon???

well if that's an acceptable fit to you then I guess there is no problem.

anyone have a different model (other than 20 or 29) storm lake barrel to check fit of?

guide rod only sticks out further IF the slide is put on the frame. Otherwise it lines up correctly.

oh man that's stupid simple.  how can they not know this!

ha  after reading the CCF thing I'm not sure what to do anymore! lol

I agree, but good luck getting them to believe you or understand what is going...well now that it's posted on a forum they might take notice.  But I made a video for them and wrote it all out before and they (David-owner and April) just didn't comprehend it.

Their response to me was completely unprofessional. Like I said it was frustrating and sad. Aren't the cuts on the SLB barrel beautiful??!!?  Anyway, I will not buy from or deal with them until attitudes are changed.

yeah I'm sure on that.

I thought it might be a number of things but everything produced same result. Also that new frame I showed in the video is straight out of the box unfired...never messed with etc etc...yielding same results.

could have shown more but it's a waste of time. They all do the same thing. April's cure is to send them all in at my expense (already sent 3 of them and they hosed that up). David's cure is to "have one of his "techs" look at them all..because he doesn't have the time and that's not what he does."  He also wants the whole gun..which I replied should I send in all 4 guns they don't work/fit in??? lol

I'm not bitter or mad or trying to be a dink. The above is exactly what they said. I just think it's sad and frustrating, because they seem to have the ability (machinery) to make a hell of a barrel. The cuts on them are beautiful...they obviously must have a very high dollar cnc.

My only problems with them are they haven't figured out the feed ramp yet to get reliable feeding into their super tight chambers. The black coating just makes this worse.  And they have this weird quirk where the slide is slightly retracted on all of them...at least the 7 barrels I have which are all for the glock 20 and glock 29. I can not speak for any other models.

btw they did not offer to exchange the barrels. they did offer to refund the purchase price if I could produce a receipt...which is no problem on the 3 I bought from my dealer but the rest of them I'm S O L. 

The whole thing is just a sad frustrating waste of time and effort.

Good video.  Are you certain the slide lock is installed correctly?  What direction is the "hook" edge facing?  Can you unlock the slide w/o pulling rearward?  If it's backwards, it will cause what you are seeing, moreso with some barrels.  With my OEM barrels, it's barely noticeable at all.
