Hi guys, first this question isn't for me, but a friend. I keep seeing yes it's okay then no it's not safe. Is there any concrete data that says you can shoot powder coated lead bullets in a stock Glock barrel? The gun in question is a model 17 9mm am not certain what Gen. These will be reloaded ammo by the way. Thanks guys, my eye's are sore from reading all the data that contradicts each other.
 
Back in the day it was frowned upon to shoot lead bullets in the polygonal rifling but coated bullets seem to run ok in that type of bore.
 
Other than checking the barrel every few rounds anything to look for? I read a post from 6 years ago that said it was a Fact that there could be barrel obstruction with less that 1 mag being shot? Sounds pretty crazy. Thanks.
 
I personally don't shoot Glocks, but the guys I shoot with run all kinds of bullets through theirs. Jacketed, Plated and Coated Lead and I've never seen a problem. I know one guy that mixes his ammo up all the time and I'm willing to be he has not cleaned his Glock in at least 5k rounds.
 
I have shot at least 5K coated through my G17 along with several K plated never had an issue

Absolutely no need to check the barrel every few rounds. There’s no way to get an obstruction with less than 1 mag unless you stick a squib in the barrel. Some people post nonsense just to get attention.

It can be possible to get leading using coated bullets but that’s because the coating isn’t adhered correctly and it’s a bullet problem not a gun problem. If you notice accuracy start to deteriorate than check the barrel.

And if the barrel has some lead deposits, just scrub it, wipe it down, lube it and then get back to shooting.

As was posted above, the internet is filled with self proclaimed experts spouting tons of utter garbage.

Stay safe.
 
No trouble running coated in my g23.
Running cast in my hk usp45 shows leading after 1 mag, but coated are fine.
 
Just to clarify (really makes no difference)

Powder coated bullets are NOT the same as Hi Tek coated bullets.(different type of coating.

They both will run fine in Glock or other poly wog barrels.:)
 
People say don't shoot lead and polygonal barrels but there is a warning directly from Glock not to shoot reloads at all who pays attention to that not I.
 
I was issued a Glock many summers ago. (Glock 17 in 9x19mm) It came with the owner's manual. Nowhere is use of a lead bullet forbidden. Anything but factory ammunition voids the warranty/guarantee/vague promise, but then don't many. Many folks have made an issue of 'polygonal' rifling and lead bullets which I find ridiculous on at least two grounds.
1. The factory fresh owner's manual had a dire threat about any reloaded ammunition but nothing about lead specifically.
2. Despite the claims, the rifling is closer to Metford style than the geometric polygon as found in Heckler & Koch arms. By the way, Metford's rifling resulted in less fouling using black powder.
 
i have shot many, very many cast lead, plated, and powder coated bullets in several 9 mm and 40 s&w glocks. the cast lead and/or powder coated are from weight weights. the plated bullets are from extreme. never had any problems. at one time many mango seasons ago i was all so fooled about don't shoot lead on glocks and went out and bought many different after market barrels to shoot lead.
 
You can absolutely shoot coated and traditionally lubed cast in Glocks including stock barrels with no problems. There's no end to the amount of nonsense and absolute lies I have read contrary to my personal experiences and those of others regarding this subject.
 
Thanks for all the replies. When I read the older post that less than a mag could cause an obstruction I said "Houston we have a problem here". Knew that didn't sound feasible. Thanks Mac

More of a problem with "rationally lubed" lead bullets in a polygon barrel is they tend to "skid" and not grab the "rifling"

The whole issue has gone on since Gaston was born!
 
If you get the hardness and size correct you can shoot plain lubed lead through a stock barrel. Many have done it for years with no issues, but you have to have the lead the right hardness and correct size. I have shot thousands through a few Glock 17’s with 0 issues once I got the hardness down. Now I powder coat mine and I have fired at least a 5 gallon bucket of bullets since I started and have no issues. My edc G17 gen 3 has probably seen 3000 down the factory barrel since it was last cleaned and the barrel is barely dirty. I also run the sesame bullets in 4 other 9mm pistols and an AR-9 with no issues.
