For all of you "unsupported barrel" haters out there.

Running reloads out of your Glock is an option. It comes with a slight increase in risk due to the minute reduction in support. I know a couple guys who've reloaded the same brass for their Glock's for over 5 years now. Neither has ever had a KB. You have to pay attention when reloading and watch for worn or weak brass a little more diligently over other makes/models.

Everything has its ups and downs. The possibility and/or increased risk of brass failure with a Glock is a trade off for greater reliability. You can't win them all. What traits are important are directly connected to the role the pistol will be deployed in. Hence the importance of understanding and defining the PURPOSE for YOUR pistol/rifle/shotgun.

Its awfully difficult to determine what is and is not necessary on a firearm if you don't first have an idea what it will be used for.

WWIII,

You have a point. Keep in mind, that Glock designed their pistols to use factory new ammo only. Much like every other manufacturer out there. When using factory ammo, there is no issue. Even with a supported barrel, reloads are a greater risk.

Glock kabooms can (and occasionally do) occur with factory ammo. Factory ammo is not 100% defect-free and it is not improbable to come across a defective round (or even an entire defective batch of ammo). Less chamber support results in a lower margin of safety when you encounter an overcharged round. To use automotive analogy, every car is equally safe as long as you don't crash. If you do crash, however, you would rather be in car with the best safety features.

True, the same can be said for all makes and models of firearms. ON a side note, all the chamber support doesn't seem to mean sh*t with Ruger pistols. Place your bets and roll the dice...

I think Glock made the term “unsupported chamber“ particularly well known. The fact is Glock chambers are far less supported than most, maybe all pistol chambers. One only has to look at the bulge in the bottom portion of brass fired from a Glock to understand why Glock chambers have become synonymous with that term.

I have a few thousand once fired brass from my G22 that I haven't inspected yet for reloading. But I have started in on my G37 brass, I didn't find any bulges at the bottom though. When I start in on the the .40's I'll give them an extra look over.

Hard to tell from the pictures but his brass is looking pretty well used and I believe he said he was running max loads, so if he kept doing that with the same brass continuously its going to wear out quite a bit faster.

Max load, weak brass, massive unsupported chamber = KABOOM!

Looks pretty well supported to me. Ruger 9mm.

All my brass is in immaculate condition not a single buldge by even the slightest bit.

I was referring to the two sticky's regarding recalls on Ruger pistols and the other thread about a subcompact Ruger that blew up.

several years a go i did some bowling pin loads for a friend (work up test for chrony )he did not have the dies yet ( shot 9mm) that he had just bought (45acp used 1911 with comp) only partially supported 20 or 22 lb spring

don't remember the load 230/240/250 loaded hot

but when doing the test one brand of brass was softer and ballooned the brass:eek: never had a failure but did stop using that brand of brass

note
when i pick up range brass ( not my own ) i single stage dereprime it
if i find some that is hard to resize :eek: i toss it into my recycle pail

ie 45 acp .014 bigger than normal ( bulge ) toss
40acp ( bulge ) toss
