Shooting lead reloads out of a glock factory barrel is not recommended

Myth

Incorrect. Glock does not recommend this, and may consider it a reason to void the warranty.

As for the "myth" of excessive leading, it can be definitively shown that the polygonal rifling in a factory Glock barrel results in excessive leading (versus a traditionally rifled barrel) when shooting non-jacketed bullets. Excessive leading can result in increased pressure. There are stories of factory barrels failing after as few as a few hundred rounds without cleaning, but there are also many shooters who report no problems running non-jacketed bullets on a regular basis.

Personally, I think it's a good idea to spend the $125-150 for a drop-in after-marked barrel. It's a small price to pay to just be sure.

Prove it. I like to see someone post either an official Glock letter or owner's manual stating no lead bullets. Where does it say you can't use high quality commercially manufactured lead ammunition?

BTW Bruce Gray when he was still working with Oregon Trails Bullets wrote a section in their reloading manual on using Oregon Trails bullets in a Glock with OEM barrel.

Hey look, I didn't mean to start another argument its just I hate to see when people ask a question about competitive shooting with a Glock that within a few posts someone recommends a replacement barrel. In my opinion they are not necessary and will not do anything for your game, and the same goes for high dollar triggers. Who am I to give my opinion? I'm a Master in USPSA Production and I'm a GSSF Master who has won all but 2 of the GSSF matches I've shot. My Glocks only have better sights and reduced power striker springs in them. With a stock barrel you can put every shot into the X ring on a tombstone target at 25 yards and that's more than good enough for IDPA or USPSA. I've shot over 10 thousand rounds of lead and plated bullets through my G35 and G17 both with stock barrels and I have never done more than pull a boresnake through them. Some of the lead bullets were .358 dia for .38 special and they chambered and shot fine. I'm not alone either, I friend of mine is sponsored by a molly coated bullet maker and has easily shot three times as many rounds as I have through stock barrels with no issues. Now that may not be good enough from some and that's ok. Please don't post about all the "potential" problems a new person might get into, hell the new person could fall and break his neck on the way the garage to try reloading. Life is full if risks. We're adults here and should do all the necessary homework when dealing with guns and ammo.

If you want to complete with a Glock by all means go do it. Take the gun and ammo you have and go shoot. Once you have a match or two under your belt you'll know what you want to change.

If your game does not have a minimum caliber or power factor get a 9mm, everything is cheaper with nine.

I never questioned anyones credentials or shooting experience. I know plenty of people who shoot lead bullets out of glock barells. No problems reported. But the manufacturer does not recommend shooting reloads. Plain and simple. I'm not trying to start anything with you. I may not be a grand master but I know a little bit.

Whats the reasoning for running moly coated lead?

Whats the reasoning for running moly coated lead?

Moly significantly reduces lead residue (as compared to plain lead).
