Multiple 9mm Glocks have handled 250,000+ rounds. 45 ACP is lower pressure so I would think it would last as long or longer.
I believe he was asking about the barrel, not the platform in general with regular parts replacement.
Yes and those glocks have not had their barrels replaced, just their springs (and I believe a connector or two).
I do wonder at what point accuracy suffers though. I talked to a guy who has personally hand loaded and fired 70k rounds from his 23. He said he did have to replace the factory barrel at some point due to a noticeable decline in accuracy. I did not ask him when that point was (wish I did).
The accuracy will eventually decline, but the barrel will remain usable.
It's rated for as many rounds as it delivers acceptable accuracy in the judgement of its owner. When the accuracy declines past the point that the user is willing to live with, then it can be easily replaced.
Barrel life depends on many factors: pressure, heat, powder type, powder charge weight, etc.
If you are loading full power loads using Titegroup and then rapid-firing them in 100 degree heat your barrel won't last as with long as with low power loads using 231 shooting them slowly in 60 degree weather.
I would think the 23 and the 32 would have shorter barrel service lives than the 30, as would any of the 10mm models. The .45acp cartridge, especially in the range ammo commonly used, is pretty gentle on barrels.
Let's see - if I shoot 5 boxes a week, 50 weeks a year, for ten years, I'm halfway to that 250,00 round mark.....
This. Many people mistakenly think velocity is a barrel killer. If that were true, barrels would wear out at the muzzle first. They don't. they wear out at the chamber end first and that's primarily because of heat induced erosion.
A contributing factor is as stated, type of powder. Double base powders are particularly prone to causing heat related erosion as are most any powders with a high flame temp. In the early '80s, using almost 100% Hercules 2400, I eroded the forcing cone on a Ruger Redhawk to the point the barrel has to be replaced. That was around 20,000 full house rounds.
Although less of a problem with modern semi auto powders, the phenomenon is real. But as easily as Glock barrels are replaced and as cheap as they are it's a non problem. I'd think the great grand children of run-of-the-mill shooters might have to replace their barrels sometime in the next century ... if ever.
At present prices, I suspect that there a few who will ever see one wear out. Glock has a Model 17 with 348K rounds through the same barrel- even if the G30 barrel goes half that number, you have probably gotten your money out of it and then some...
I've been shooting a Glock 30 for about three years, probably at least three or four thousand rounds of 230gr. FMJ through it, and I can't see any noticeable wear yet.
Glock barrels are cold hammer forged. They will last if treated right. Most of the time the pistol will outlast the owner.
