Glock 17 Slide burr

http://m4carbine.net/picture.php?albumid=476&pictureid=2464 Bought this used and was wondering were this burr is coming from. Nothing on the receiver show's any contact and slide stop looks fine also. What else should i look for. Also should i not shoot it now? Thank you

I'm not seeing a picture in your link.

Somebody dun fumbled the slide and dropped it on a hard metal surface. Considering that is a bearing surface that sees nothing but linear motion on the frame, that type of damage wouldn't occur under normal or abnormal use of the firearm.

My suggestion? Take a small file and file off any metal that has been displaced past the surface that might catch, and fire away! It's just a small ding.

To further add to this, it appears as though maybe the previous owner was cleaning the firearm and had the slide sitting on a table with the barrel in it but the recoil spring assembly removed. Then knocked the slide/barrel off of the table and the assembly landed on the barrel lug thus forcing the now out of place barrels hood against that part of the slide.
Of course it could have been aliens too.:eek: Just stone the displaced metal flush with the rest of it and keep on trucking.

Oops, "stone" is the right term, not file. I hope you didn't take a 12" bastard file and removed half the slide. A little boron carbine hone or similar should flatten it out.

thanks guy's; I"ll hone it out.

It comes from the locking block slamming into the slide when you fire the pistol and the frame flexes during cycling. It'll get to a certain point and then get no worse. It's much more noticeable in.40s, .357s and 10mm Glock pistols.

Should I still hone the burr out or let it run it's course?Would you say that it has alot of round's through it?

Usually after 1-2k rounds it'll be done growing. Smoothing down the burr won't hurt anything.

Would you reblue after?

This is indeed correct and is even covered in the Glock armor's class

My Glock 17 has the same burrs. I was also told that it's mentioned in Glock armorers class and is usually more obvious in the .40s and .357s. I haven't noticed them getting any bigger as I shoot it more. I'm going to keep an eye on it but I'm not going to worry about it.

Would you reblue after?

No. Just knock off the edges and leave it be. It's a Glock thing and completely normal.

Are we sure that is from the locking block?

From my own experiences what i have seen is usually somewhat symmetrical wear and it is usually forward of that location, ie towards the front of the locking block.
