Lead bullets in Glock?

Because of the type of rifling that a Glock has, Lead bullets will cause deposits rapidly and are a pain to clean out. With a build-up of lead in the barrel you can also cause increased pressure if you fire alot of lead and dont clean.

my 2 cents.....
 
apperently if you change to an aftermarket barrel without the polygonal rifling you're good to go- ask yourself- how much lead do i go through and is it worth it?- and i don't think the 1 in 10 jacketed trick will work in this case
 
Lead bullets in glock

Welcome to the club of the polygonal rifling barrel. I own an H&K usp 9mm pistol and I have not the leading problem you have even if I cast my own bullets. The problem I had was a tumbling bullets problem caused by the polygonal rifling barrel. I tried a hundred of receipes to solve that but without succeed.
Someone told me that I can sell de pistol or have a new non polygonal barrel. I order from << https://68designs.net/~efkfired/index.php?PHPSESSID=e696458f6bb4b08720aefda729b6327e>> a new barrel and there is now no leading or tumbling problem. It takes 11 days from the day I place the order to receive my new toy. No fitting at all. I only drop it in the slide and everything was perfect. I had over 500 rounds shooted since and I am 150% satisfied with the result.
I choose that option because I like very much this gun. Otherwise I will sell it and try something else (non polygonal barrel).

Lead bullets in Glock

Try shooting jacketed bullets intermittently while shooting lead bullets. I haven't had a problem with the .40 S & W cartridge shooting lead in my glock but to be on the safe side and to avoid ugly cleaning sessions I shoot a few jacketed loads during a long shooting (with lead) session. The last mag through the gun has jacketed only in it. There is no lead remaining. This may not be the prescribed procedure but is has worked for me.
