Pentagon on my Glock?

From what i've heard... (Don't know if it's true, it's only a hint for you)
The polygon could only signifies that the barrel has polygonal rifling.
Normal Rifling on the left, Polygonal Rifling on the right...
Polygonal rifling have a few advantages:
* Less bullet deformation, resulting in reduced drag on the bullet which helps to increase range, accuracy, and velocity
* Increased barrel life and reduced buildup of copper or lead within the barrel
Here's an example on what you find on your barrel:

Could be Glocks proof stamping?
As it is actually on the barrel itself, yes it could be a proof stamping of the barrel!

Really?? Then why does Glock void warranties for shooting lead??

german proof stamp, but I thought this one was for softairguns and .177 air guns only.

Maybe on normal rifling barrels...
But on Polygonal barrels, there's no problems!
Ummmmm, no? As far as I know Glock will void warranty on pistols that have fired non-jacketed. In addition, I don't think Glock has any standard rifling barrels, they've always been Polygonal rifled if I am not mistaken. Someone please tell me I am wrong. I've been keeping lead shoots to a minimum for this reason alone...well, and I've heard from some that lead out of a Glock is just bad news (Polygonal leads more quickly)
As far as I know Glock has produced both types of barrels, pretty sure most if not all in North America are polygonal though. I believe the polygon on the barrel indicates just that - a polygonal barrel (as has been previously suggested a few posts back)
