    I recently installed a new aftermarket muzzle treaded barrel on one of my Gluck pistols. The barrel was made from 416 stainless steel. After about 40 rounds, the barrel split about two inches from the muzzle down the barrel towards the chamber. The split started at about where the treads started on the end of the barrel. I contacted the manufacturer, and of course they wanted to see the barrel. I was shooting from the standing position two handed, using new WW 9mm ammunition. When the barrel split, I saw a flash at the muzzle and noticed that my muzzle tread protector was missing. I suspect that the split came from either a loose tread protector, or a faulty barrel. None of the 40 rounds sounded unusual. The first five shots thru the barrel went into the same hole, and then the group opened up. I could not get the gun sighted in after the first five shots. Now my question. I had to cut the barrel in half to get it off of the gun. I thought wow, this will be a job, but the hacksaw went thru the barrel like hot butter. It felt like I was sawing thru aluminum. I have never hacksawed a barrel before, but shouldn’t it be harder to cut? I wonder if it was ever heat treated?

    MOST LIKELY 416 STAINLESS..... which is very...very, easy to machine.

    Who's cheap ammo were you shooting at the time of barrel failure??????

    There is some ammo meant only for use in submachine guns not pistols. you can run into that a lot, by using 3rd world surplus mil 9mm. Foreign 5.56 has caused some problems in AR clones, and there are warning letters posted trying to warn the masses.

    You were shooting from a standing position and put the first 5 shots thru the same hole? From what distance? Out of a Glock? With cheap factory ammo? I'd have to see that to believe it.

    There is nothing wrong with 416 stainless barrels, it's the standard in stainless steel barrels, and comparable to 4140 when using it at the same hardness levels. I would guess a defect in material, or it was never heat treated after it's annealed free machining state. The only way to prove that would be to take it to a machine shop that has a rockwell hardness tester. It should read 34-39 Rc.

    I was sighting in the pistol for the first time. I was shooting new WW 115 grain roundnose. The barrel had the thread protector screwed on the end of the barrel when the mishap occured. I always start a new handgun sightin at about five yards. Grntitan, trust me, I could shoot apples off the top of your head all day long at five yards, even with a Glock. 221, the barrel was made from 416 stainless. Do you think it should of been that soft?

    Dear Unsingle,
    Where did you obtain the info that the afftermarket barrel was made of "416 Stainless"? AISI 416 Stainless or European "416 Stainless steel" or Chinese "416 Stainless"?? or a German "416" They are all slightly different in alloy composition and CARBON CONTENT! Due to the invasion into the US of foreign supplied steels and the great differences in cost and QUALITY, all kinds of problems have surfaced.

    Send that barrel back to the maker for his examination and see what his explanation is.

    From your description of the failure, I believe you have a defective barrel.

    BL350 - I got the information about the steel from the manufacturer. The first thing they said was that would like to look at the barrel to be sure it was the correct hardness. I will wait and see what they have to say. I hope they just send me a new one, but I have lost some confidence in the product.

    Unsingle, can you take a picture of the split part of the barrel and post it here?

    GRNTITAN,
    You called the OP a liar unless you saw the target. That is not what people with any decency do. If you don't think those shots are possible, keep your opinion to yourself.
    Regards,
    Ray

    Ray,

    No i didn't call him a liar. I said "You were shooting from a standing position and put the first 5 shots thru the same hole? From what distance? Out of a Glock? With cheap factory ammo? I'd have to see that to believe it."

    He answered, "Grntitan, trust me, I could shoot apples off the top of your head all day long at five yards, even with a Glock. 221, the barrel was made from 416 stainless. Do you think it should of been that soft?"

    To which i left it alone as he answered my question and didn't get all out of sorts as you did.



    If i have no decency in your eyes, i will lose no sleep over it. This is a public forum and i am as much entitled to my disbelief opinion as you are of me having no decency. Perhaps if you don't understand that, you should keep your opinion to yourself. Think??

    I have some good pictures if I can get them to load. Here we go:

    The only damage was at the muzzle of the barrel. No signs of pressure anywhere else on the gun or brass. Looking inside of the barrel, it looks like the rupture started where the barrel has been reduced for the threads.

    Just thought I would say that i'm darn glad it was not more catastrophic when it let go and that you didn't get injured Unsingle....i had an extended choke from a quality maker well known to us all who i wont name split the same way in an Inv.-Plus barrel..luckily though hard to get out it didn't harm the barrel and the company made good with a new choke tube

    Did you find the thread protector and what did it look like? I'm guessing you won't name the barrel manufacture until they give you answer on if they will make it right?

    Before you send the barrel in, have it hardness tested. Once the barrel is in the hands of the manufacturer, it's quite likely they will not give it back to you. You might want to get it independently looked at by a competent gunsmith as well. Also contact the ammo manufacturer and send the ammo to them along with a photo of the barrel. What I'm getting at is to cover all your bases, because the barrel maker may try to blame the ammo.
