I already posted that link. There are a lot of reasons for KB's and they also do happen in other types of firearms, i'll admit. I'm an avid shooter and have been since i was very young and have never seen a firearm KB up until a guy three lanes down from me had his glock 19 blow up on him. That incident is the main basis for my dislike for glocks considering the owner was using brand new ammo, and the firearm had less than 500 rounds fired through it. Most of all, it was super clean... much how i keep my weapons. So that rules out two of the "causes other than a chamber which is not fully supported".
I also dislike glocks because they have terrible ergonomics. They just don't feel right to me. My Springfield XD and HK USP 9mm are far more comfortable in my hands in every single way, and the triggers also are excellent for a poly pistol.
Perhaps i'm biased... but only due to experience. If I had to pick a 'work horse' pistol for carry which i had to put enough faith in for the protection of my life and of others... it definitely wouldn't be a glock. I'd pick Sig, HK, or Springfield XD. (for a 9mm poly pistol).
If it were a 1911, i'd pick an Ed Brown if I could afford one. I'm not a big fan of .357 sig, .40, or 10mm calibers. While a .45 ACP has a very heavy bullet and tons of punch, if you work out the physics... the kinetic energy of a 9mm is roughly around the same as a .45. Plus you can carry more 9mm in a magazine than .45 acp.
But in the end.... my main firearm for home protection is my 12ga Benelli M-4 semi-auto... the main shotgun used by the USMC. You can fire off 8 shells before the first shell hits the ground it shoots so fast and reliably. hoo-RAH!!!
