My G20 has a gouge at the top of the chamber, approximately 1/4" toward the muzzle. It appears to be a pin-head-sized gouge. It causes a round being pulled off of the magazine to get caught on the rim of the brass case. This stops the round from chambering.
How can I push the displaced metal back into its divot? If that is not possible, must I polish away the offending thorn? Is it best to take this to a gun shop, or send to Glock? Tenifer, you know
Slightly undersized dowel rod. Glue on a series of 400, 600, 800, 1000 grit wet/dry finishing paper.
Keep wet with water.
This is done with hand power, not a drill.
Is this a brand new weapon? I've seen a wart on a cast striker block from a Kahr pistol. That really made the trigger terrible, but barrels aren't cast, are they?
I am sure you could send the barrel to Glock for a replacement.
Rogn, I like the idea of peening it to its original position. Please explain. I don't know how deep Tenifer goes, but I'd like to keep all the material rather than grinding it off. The barrel is OEM; the pistol is preowned. I'll try to upload a picture, buy my lighting is poor, and I don't have a micro lens.
The gouge was in the barrel when I purchased it, but I did not notice it until I first shot it. Prob not Glock's responsibility. It affects brass in that it stops the round from chambering. No damage to the brass.
I may send it to Glock for service. I'd like to keep all original, Glock, and parts designed for the G20, as I want to avoid any legal problems if I must use it to take out a bad guy.
I understand your concern, I share it with you also, but the problem you are experiencing is an adequate explanation for the switch. Additionally the barrel swap to replace a damaged part with a barrel in kind and substantially identical to the original is hardly a compelling argument. This isn't much different than replacing OEM metallic brake pads with aftermarket ceramic pads, which many car owners do with no real need for consideration for potential exposure to additional liability.
I would be more concerned if you were adding a comp, lightening the trigger, or adding a "kill 'em all" slide plate.
Thanks, cciman. If I can't peen it, or grind it, or otherwise remove it without damaging the barrel and its function, I'll buy a newer version of the barrel with the supported chamber.
Yeah, but it'll be fun on the range...a little extra speed from the longer barrel makes for a lot of fun at 100+ yard targets.
I spend most of my range time banging on the 150 yard steel with my G40.
Hell, I went through 26 rounds with my G32 on the 150 yard steel (12" x12") the other day, first range trip for that pistol... I hit the steel 9 out of 26 times, not bad for iron sights, lol.
Im not sure I understand all the details. If you purchased the gun "new" then the barrel defect is Glock's responsibility and they would be expected to stand up and replace said defective part FOC. I would certainly contact them with your issue. If you have to replace the barrel, any direct replacement barrel should not cause any raised eyebros. I think most replacement barrels are superior to the factory issueas far as chamber support and potential accuracy. "Most"
