Hello,

I purchased what I thought was a drop in barrel for my model 19.  A storm-lake 2 port.  I also purchased your book for help with this installation if needed.  I am not sure if the barrel needs any configuring or not.  Your book didn’t offer any help.  You just said in the book to add the drop in barrel at this point??  I put the barrel in and had problems with cases blowing out part of the sides near the primer ends.  I removed the barrel after a few rounds acted this way.  Stock barrel has no problems since.  Thanks for your help.

Hello, and I’m sorry to hear about your trouble.  It is impossible for me to recommend specific procedures for every accessory in the book.  I’ve got to rely on the manufacturers to be honest about “drop-in” or not.  On a case-by-case basis, I am glad to help if I can. 
 
The problem I think you are describing can be very alarming.  Are you shooting reloads?  Is the slide returning fully (in battery) after each shot?  How old is your recoil spring assembly?

Morgan,
 
 Thanks for the reply.  I was shooting American Eagle 147 grain FMJ Flat Point rounds.  They were a box I purchased years ago.  Recoil seemed excessive and I am not sure if the slide was returning fully prior to other shots.  Is it possible if there was not enough lubrication on the new barrel to cause this? I purchased the gun used in January.  At that time I was told it was gone over by a Glock reseller in Texas and found to be in perfect condition. I tried some of the rounds in a Ruger P89 and Ruger SR9 as well and didn’t experience any of the case blowing out with them.  I am going to send the remaining rounds with the blown cases to Federal for them to look at. 
 I haven’t tried the storm-lake barrel again with any other loads yet.  I wanted to be sure there wasn’t something I needed to do or check on the Storm-Lake barrel first.  I still have the cases if a picture of them might help things.  I have fired the stock barrel with 115 gr loads since.  Could this have been an ammuntion caused problem?

Dane,
 
There’s nothing wrong with the gun.  I’m thinking the barrel is not allowing the slide to return fully into battery.  With the gun unloaded and pointed in a safe direction, put the SL barrel back in.  Rack the slide and ride it back slowly.  Does it easily close all the way?  Do this with the muzzle pointed straight up too.  Let me know what you find out.

Morgan,
 
I tried the procedure you asked me to.  The slide would seem to close all the way with what seemed like a pop of the barrel while it was rising near the end of the slide movement.  Also running my finger along the top of the barrel chamber to slide contact area it seems the junction is more noticeable than with the stock barrel. Performing the same test with the stock barrel there isn’t the same pronounced pop near the end of the slide movement.

Dane,
 
My thinking on this is that the only way you can have case failure with new ammo is to ignite it too early.  That can be done with a stuck firing pin, so you get slam fires:  primer is hit as the slide returns instead of when the trigger is pulled.  Weak recoil spring, so the slide does not close or bounces open.  Or the barrel lug is jamming and preventing the slide from locking into battery.  The last one is what I think you are experiencing.  The non-stock barrel is leaving a gap that leaves the case under-supported. 
 
Go ahead and send me a photo of a blown case.  I’d like to see it.
 
We’ll figure this out.
 
Morgan
 
Dane,
 
It looks to me from you photos that the gun is firing “out of battery” or “before the damned thing closes all the way.”
 
This can be dangerous.  I would contact Storm Lake. Tell them what’s going on.  They may send you a new barrel?  There is nothing wrong with your Glock. 
 
You have two choices:  Do a little work on your own, or you can talk to a qualified gunsmith.  You can install the Storm Lake and rack the slide a hundred times.  This will not damage your slide.  It is much harder than the barrel.  This alone may solve the problem.  Areas of wear will appear on the barrel.  You can polish these gently with a product like Flitz or Semichrome.  Or, you can have a gunsmith do the same thing.
 
Difference?  If the gunsmith screws it up, he may buy you another Storm Lake Barrel… so you can go home and try again.  Plus, you won’t see your gun for a month.
 
I would go in intervals.  Rack the Storm Lake 100 times and see if it cycles any smoother.  Then polish if still rough, or rack more times.  Do the muzzle-up test to see if it goes into battery any easier.
 
You are not going to wear out your Glock by doing any of this.  Glocks are tough machines.
 
Hope this helps,
 
Morgan
