I have been told you can not reload brass shot in a Glock because the shell is not completely enclosed by the chamber therefore it allows the brass to swell. Can anyone give me any info on this. I am thinking about purchasing at Glock 21 but if I can't reload the brass or if it will not shoot reloaded ammo, I will bite the bullet and purchase a Kimber. Any help will be appreciated.

I own a Glock 21 and a 30 and shoot MY reloads in both of them. I reload my 45s near or at max and have never had a case head failure. However there are no guarantees on reloads and we all must reload at our own risk.

In order to enhance reliability, Glock barrels have undercut chambers which do not fully support cartridges - a small part of the web of the case is exposed. If you take a look at cases which have been fired in a Glock, you may notice a bulge in the web where it was unsupported.
Given the almost legendary reliability of Glock pistols, this constuction is not a problem with factory ammo, and probably not an issue with ammo reloads that use cases not previously fired in a Glock. Using small base dies may also eliminate the bulge (don't know, haven't tried). Regular dies apparently do a good job.
Because of the unsupported chamber, there is a general caution about using high pressure ammo (+P). Many people do in any case.
One solution to the "problem" is to spend an extra $100 and buy a barrel with a fully supported chamber from Lone Wolf Barrels (among others).

If the brass is cracked don't load it again--Many auto's have unsupported chambers
