People have posted lots of stuff here about care in reloading. Yes, you need to be careful reloading but that isn't the issue here. You shouldn't reload for a Glock because the guns have oversized chambers and unsupported feed ramps - and if you use brass more than once - and the weakened in the feed ramp area from the first firing happens to line up a second time with the feed ramp (even after proper case resizing) - the case will fail. Don't believe me, believe Glock. They specifically say DO NOT RELOAD FOR THIS GUN. Lee also says that their Bulge Buster kit cannot repair bulged case from firing in a Glock LINK

Every new guns I bought came with instruction booklet saying "do not use reloaded ammunition" sort of deal. It just a CYA statement from companies.

Thousands of competition shooters reload for the Glock including many of the top sponsored shooters in the world, all without incident for many years. Reloading issues for Glock are no more frequent than for any other brand, care must be taken regardless of brand or caliber. As stated earlier all brands warn not to use reloads, for 2 reasons, 1: to cover their ass and 2: to sell factory ammo.

It's also pretty simple to not load at or above SAAMI pressure. Most load data max load is around 31000 PSI. SAAMI lists a MAP at 35000 PSI.


http://www.saami.org/specifications_and_information/specifications/Velocity_Pressure_CfPR.pdf <==Page 5 on that.

Here is a sweet little wiki page that has a blurb on 40 S&W case failure, Note the unsupported case they show is in a Beretta.

https://en.wikipedia.org/wiki/.40_S&W

Now if you go deeper into this you'll find that to get into the major power factor loads your not even at max charge on reloading data. Do you understand that?
Regardless I run a minor PF load 75% of the time and my loads charge weight is 9/10ths of a grain lower than the "Books" starting load.

Reload for your Glock But be safe about it, Know your powder drop, Know your load.

I should clarify that I'm talking about .40 S&W reloads.

They are just showing a picture of a Beretta 96 feed ramp, they are not saying it is unsupported. In that picture the case is not inserted all the way into the barrel, there is a notch in the other side of the barrel for the extractor allowing the case to go in flush which allows the extraction grove to be in past the top of the feed ramp. On the unsupported Glocks the feed ramp goes in deep enough that part of the case above the extraction grove is left exposed.

Every manufacturer warns the purchaser that all warranties will be nul and void if unauthorized modifications are performed on the product. This goes for car, motorcycles, pleasurecrafts and firearms are no exception. If Glock insists no reloads then shoot at your own risk. Very simple instructions in my eyes.

It's fully inserted and the feed ramp goes way past the extractor groove.

Oh look I have a Beretta too....It's a 9 and The same as the pic of the .40

Also while fiddling with the Beretta I noticed that the chamber is a little generous. This could be that the pistol is a older gen though. it's a 92FS that's 21 years old.

Very strange, I have 3 beretta 9mm and a 40 with barrels for both 40 and 357 sig and they all go almost flush. I dont know how the slide would close all the way with the case still out that far plus the extractor grove is not even into the notch where the extractor would sit.

PS: I just measured the inside of a case and the part of the case that holds the powder doesnt go all the way down to the extractor grove so even in your pic the part of the case that holds powder is still in past the end of the feed ramp and is supported.

Also googled a couple pics that show the difference.

There exists manufacturers that will give a customer a goodwill warranty almoat regardless of circumstances, it's why I suggested he contact Glock about it on the first or second page of this thread.

BS.

This is a pic of a sized case in the chamber the barrel is in the slide and the extractor is seated in the groove of the case. The recoil spring is removed and the lock block pin has been pushed in to simulate lockup and to give a clearer view.
So unless your slide does not have the cutout for the case head I don't believe you.

Then have a look. Live round in chamber, feed ramp almost flush with edge of extractor grove, almost none of the case above the groove showing.
