Any scratches in the bore?

[JeffLrrp]

[Forgive me if this is posted in the wrong area.]

My novice friend just recieved his new Glock 19 a couple of days ago. We went to the range and put about 400-500 rounds through it, some of it quite dirty ammo. When we got back to his place, I had went outside to take a call and he started dissassembling it for cleaning. I just got back from the call when I noticed he was trying to run the factory supplied brush from glock through the barrel, dry nonetheless !. He had only run it through about twice before I caught him, and then per my instruction proceeded to lube the barrell and brush before inserting it.

Now he his worried about scratches in the bore. Does anybody know if 1-2 times with the factory brush will scratch the glock barrel?

Thanks,

It's not going to hurt it. The system is designed so that the metal in the brush is softer than the metal of the bore so that doesn't happen. No worries.

[JeffLrrp]

he'll be relieved. Thanx

I don't think it should cause any problems, More important thing is did he run it from the breech end? A brush ran from the barrel end can actually get stuck in the barrel. Remove the barrel from the gun, run a couple of dry patches through it to make sure it is dry and then look down the barrel from the breech end while holding it up to the light. You will be able to see if there are any deep scratches in it. Since the barrel is steel, and the brush is probably bronze or brass I wouldn't expect to find any damage.

The factory brush is nylon. No harm done. The Glock bore is pretty durable but stick with bronze bristle brushes. No ss or tornado brushes should be needed with the Glock's polygonal rifling. If he uses Miltec or Slip 2000 on a regular basis, cleaning can be done with patches alone.

thanx for the quick replies, everyone. You sure are a smart bunch.

yea, even a dry brass brush wont do any damage. a lot softer than steel. a nylon brush certainly not

[SonofASniper]

That nylon brush isn't going to hurt it. I have taken the nylon brush and done a quick run through the barrell dry several times when I need to clean out the barrel real quick. When it is time for serious cleaning, then use a brass or other metal brush with some good cleaners.

edit to add: Don't over lube that glock by the way. They are not a very oil thirsty gun.

While we're on the subject here.
Even the Stainless steel bore brushes are soft (partially annealed) Stainless and they can be run through the bore (wet or dry) also without scratching or causing damage to the bore.

I wouldn't worry about it even if it did.
