.357 magnum isn't high pressure...riiiiight. Anyway, thanks for reading my entire post. The high pressure COMBINED with the case geometry leaves more potential for issues after a setback than the calibers you mention above. Lets go through the list...based on the specs you provided. .357 Sig - no argument there, the OP even said there may be an issue and it is derived .40 S&W. .45 ACP is 40% less pressure to start with. 9mm is the same pressure and similar length to 40. However, the surface of .40 cal is 25% larger than the 9, so the case volume decreases at a faster rate relative to 9mm as the bullet is set deeper into the case. That is why setback causes pressure to reach dangerous levels faster than 9mm.
All that being said, I'm not trying to say .40 is a defective or bad design. It just has less safety margin in this circumstance than some other calibers. I also agree that Glock is a great gun. However, you freely admit that older Glock 40 barrels have a bad chamber design. I simply said ANY poorly supported chamber increased risk. Individual owners of ANY pistol should drop a bullet in their barrel and compare case support to the photos above. Honda Accord is a safe car, but not as safe as Mercedes S600. And if you plan to push the limits but still want the utmost in safety, consider ordering the S600 armored.
WTF? Good job of making a simple subject seem complicated. I read your post and simply posted facts that are indisputable. You can look them up and get the same numbers I posted. You have a problem with a post that doesn't take sides, just states facts and then you ramble on as if incoherent. Plus you need a remedial math lesson; "the surface of .40 is 25% larger than the 9", how did you come up with this stuff?
