Do glocks shoot lead?

[dogbear]

I was looking at a glock 17 the other day and a guy came up and told me glocks are good guns but you have to change the barrel if you want to shoot lead bullets in them.I told him I hadn't shot more than 100 rounds through a glock but it didn't have a problem,and I had never hear of that before.I am sure this isn't right since alot of people on this forum shoot glocks alot.Has anyone ever heard of this before?

This is mostly true. If you shoot much lead at all, the polygonal rifling will get very fouled, and probably cause pressure issues. This is third hand info, but pretty well accepted.

Correct.
Exposed lead (non-jacketed) bullets should not be shot through a Glock.
The rifling in a Glock is hammer forged as opposed to traditional rifling which is 'cut' or machined.Forging typically leaves a groove that is shallow in comparison to 'cut' rifiling.
The Forged rifling provides a tighter seal on the bearing surface of the bullet and is more sensitive to lead buildup.
Although I can't recall off the top of my head any *official* position from Glock on this matter,my experience with metallurgy and firearms would lead me to follow this line of thinking.

Thanks for the explanation.I am at work so I don't have the box with me.But are the winchester and blazer target loads we get from acadamy that are $3.50 -$4.88 a box jacketed?

The 9mm Blazer that I bought last weekend from academy was jacketed. I was kinda worried about the same thing too if they hadn't been.

For autopistol cartridges, you have to look pretty hard to find lead rounds unless you reload. Not that they aren't out there, but they are in the minority. (.45 ACP probably being the most prevalent).

All correct, it also states this in the owner's manual. Hoov
