.... given my druthers, I'd druther have NIETHER (I like my guns).
That said.............. I think (IMHO- definitely humble- as I have only 10 yeears or so of pistol shooting (and even less reloading) experience) the glock platform in .40S&W, suffers a perfect storm of sorts, with respect to KaBooms: You take a high pressure cartridge (for a pistol) like the modern 9mm, build a platform for it, then stuff an even HIGHER pressure cartridge into it, in an effort to equal the performance of a larger, low pressure catridge (the .45 ACP). The platform, as designed, has a chamber that is not fully supported, and is hell on brass (being a high pressure cartridge) in the first place. Add reloaders, many of of whom like to see how much velocity they can squeeze out of a load....... each step along this path cuts a little piece off the safety margain designed into the platform.......... and if I have learned ONE thing in dealing with German (OK- it's Austrian, but there is a joke in Germany- The Austrians are so resistant to change that "the Germans WERE Nazis- the Austrians ARE Nazis.") Engineering, it is this: Do NOT exceed the design parameters. If it says "do not exceed 6,000 rpm", 6,001 can cause things to go pear-shaped in a hurry.
