Okay, guys, once more:
DO NOT SHOOT LEAD BULLETS THROUGH YOUR GLOCK HANDGUN, AS EQUIPPED WITH THE FACTORY BARREL.
The handgun was designed to function and perform with JACKETED bullets. DO NOT USE LEAD.
If you want a reference, well, I got the best that I could find. May not be good enough for some of you technical folks that "know better". If you want, you may speak first hand to the folks that gave me the information.
Their telephone number is 770-432-1202. In case you're interested, it's the Glock factory in Smyrna, GA.
The tech that I spoke to stated the following:
1. The factory fires 6000 rounds PER DAY through various Glock handguns.
2. The techs there DELIBERATELY shoot high pressure loads (blue pills), shoot into obstructions in the barrel, and purposely blow guns up to inspect and to analyze them.
3. The guy I spoke to said that his carry gun is a G23, with 13,000 documented rounds fired through it so far. He has been with Glock since 1990, and has been a gunsmith for 23 years.
So, I guess for all you ballisticians out there that can outguess the factory, this still might not be good enough.
I choose to heed the warnings from the guys that manufacture the pistols--DON'T SHOOT LEAD IN THE GLOCK.
Period.
