Bore Snake scatches Glock Barrel?

I recently let a friend borrow one of my Glocks for a trip to the range. When he returned it there were scratched inside the barrel. When I asked him about it he said that he used a bore snake to clean the barrel for me. Is this a common occurance for Glocks? Will it affect the function of the gun?

I've never had an issue with a bore snake scratching a barrel. I use them in my XD, 1911, Ruger MK II and various revolvers.

There is no metal in a bore snake that is harder than the barrrel of the Glock so I don't see how that could possibly happen.

Perhaps what you are seeing are trails of brass or copper from the bristles on the boresnake. Go shoot it a bit, and then clean as you usually do it and see if the "scratches" remain. As dusty14u pointed out there should be nothing on a boresnake that would be harder than the material the barrel is made of.

It's probably gunk. Have you cleaned it?

I've cleaned my G20 with both the stock barrel and the aftermarket KKM Precision barrel using a Bore Snake and have to call BS.

I am even fond of using a .45 caliber Bore Snake in my 10mm (.40 cal)--I like it tight ;)

I've never had a Bore Snake damage any of my firearms.

I Use BoreSnakes on my Glocks several times a week and have for the last 3 years. No scratches. The brass on the BoreSnake just isn't hard enough to hurt the Glock barrel.

Without seeing the barrel, I would guess that Snarlingiron is on the right track but I've never see trails left on mine after cleaning.

There is simply no way a bore-snake, bronze bore brush, or even a stainless-steel bore brush could scratch a Glock Tenefer barrel.

The surface finish inside the Glock barrel is several times harder then any cleaning equipment you can buy.

Not only that, but a bore-snake cannot scratch any guns barrel, no matter how soft it is, unless you drop the bore-snake in the sand first.
Sand might scratch a barrel, but not a bore-snake.

You can cut hard steel with soft materials like water, even light....

This is why precision shooter with SS barrels are extra careful even with soft brass jags and brushes. Too much cleaning can be a bad thing over time.

...but, in this case, I doubt a boresnake did any damage to your Glock. Are you sure it isn't just lead fouling or copper fouling?

Pics?

I will try to get some pictures as soon as I can. I have not yet tried to clean it myself as I was still kind of shocked when I first saw the "scratches". They did not rub off when I used my pinkie finger (while field stripped). Thank you for the comments I hope that you are right and that the "scratches" clean up.

Unless he has a diamond Bore snake, those are not scratches. A Glock barrel is 64HRC.

That is true enough, but under very, very special conditions not likely to be duplicated with some guy and a cleaning brush.

I don't believe a boresnake could scratch it but what if there is something foreign on the boresnake like some sand. I don't know about the rest of you but I wash mine now and then.

Likely your friend shot less expensive reloaded lead bullets in the gun and what you are seeing is where the brass bristles of the bore snake have taken out some of the lead. The polygonal barrel of the Glock has no land or grooves just flat surfaces so when the lead accumulates it smears evenly in the bore. Looking down the bore with a light you generally will not see the lead even in a heavily leaded bore as it still looks bright and smooth as steel once the powder fouling is wiped out. Push a tight patch from a treated lead wipe cloth through the bore on a jag and you will see streaks or pieces of lead.

Yes, but these methods remove a very small bit of material, only with a lot of power and focused like a razor. If you ran a bore snake through the barrel thousands of times, you could get the power part, but there's no focus. Instead of scratches, you'd end up polishing the bore.

The only other error made, IMHO, was lending the firearm out in the first place, no matter how good of a friend he is! Not on my watch.

I agree - while sorta off topic, I NEVER loan a gun to someone, unless I am standing next to them and am letting them take a few shots with it in my presence.

Maybe you are seeing the dried residue of gun scrubber? Or, he scratched it some kind of way he won't tell ya

Waterjetting is using abrasive material injected in the high presure flow so while the water may be softer it isn't the water that cuts the material. It is the abrasive compound in the water , which is harder than the steel, which cuts it. Lasers use massive amounts of electricity which amplify a beam of light to pierce and cut metals. Been programming lasers and waterjets for years as well as a machinist for the past 30 years. Don't do too much hands on anymore but still program them.

Things like that happen with a plastic barrel! :D

Don't worry about it. Glocks are perfect - it will fix itself.

There's no way whatsoever that a bore snake scratched a glock barrel. To even think so is crazy in my opinion. I run a bore snake down shotgun barrel and it always "looks" like it has scratches. That's because the bronze bristles do scratch away at the layer of carbon, fouling and crud in the barrel. Once I do a real cleaning, the bore sparkles like new without a "scratch" to be seen. If the barrel is really scratched, it was done with something other than a bore snake.

If your friend somehow got a piece of steel embedded in the Bore Snake it is possible it was used to scratch the bore of your pistol.
A Bore Snake alone is constructed of no material hard enough to scratch steel.

As noted, the finishing/hardning process used for Glock pistols produces a surface that is very hard to permanently scratch.

Sight inseen,I think a good application of JB Bore Cleaning Compound and a bit of elbow grease will remove the imperfection from the bore. HTH

Not kickin' doggies or anything like that, But... How in the world did you get your finger inside a barrel to scratch at the scratches?

The Glocks use plastic barrels, you just stretch them and put your finger in. You have to be careful though, they can turn into Austrian finger traps, you have to squeeze them long ways a little to get your finger out.

Try to keep up man!:neener:

That's a good tip about useing a waterjet and laser to clean Glocks instead of a boresnake. No scratches and those won't leave any metal behind which could cause metal detectors to go off.

Shoulda bought the Glock 7. I hear that porcelain construction costs more than what most of us makes in a month.

What does that have to do with anything. I love how a guy can come on here ask for help and have the brand of gun get bashed. It's sad that a guy can't even ask for help and give the gun brand without getting bashed about it.
Now I agree no one uses my guns unless I am there but that's a whole different thread.

As stated above, either your barrel ain't really damaged, or your buddy is lying to you about how he treated it. Them's the options. ;)

Die Hard reference meant as a joke, I'm betting.

It was a laugh at the expensive of Hollywood, not Glock.

Yep, it was a reference to Die Hard 2 as a joke. Sorry, I didn't mean to actually poke fun at the OP's choice of gun. Glocks rock. I also have a Beretta that bends the rounds down the range too. :p

I was hoping the porcelain part would've made it obvious though.
