Since I have now moved over to the dark side (Glock), I have researched the living hell out of their pistols *and yes my Glock model 7 rocks* - but on a serious matter, the Kaboom issues are due to using reloads or just "hot" loads in certain makes of Glock handguns that were designed with a rather large tolerance between the cartridge case and the barrel - this is typically called an "unsupported chamber". They do this so if ammo gets dirty or the gun gets dirty, it will still fire - which makes it more reliable in a full-on mud wrestling gun battle.
I have seen pictures of the earlier kaboom models vs. the newer models (same model numbers, different year of mfgr.) and the newer models do have tighter chambers. They are still not tight enough to stop bulging fired cases though, which is why Glock recommends their owners do NOT fire reloads in their guns. I think it has dramatically reduced the kaboom problem though. The bottom line is that the brass just expands too much in a lose Glock chamber and puts overdue stress on the brass. The feed ramp portion where the round enters simply has no support, which is where the brass fractures happen, which is the underlying issue of the kaboom (unless someone is shooting lead bullets in the poly bore, which is a whole different matter - and just as dangerous)
These problems can be solved by ordering an aftermarket barrel with a tighter chamber (Lone Wolf, KKM, Storm lake, etc.), but then if you get into a thick-up mud wrestling gun battle, you might have a jam - though unlikely.
Life is short. Eat, Drink & Be Merry!
