I've not seen or heard of any problems with the 40. I think most who had the 40 went to the 10mm. Same bullet, more FPS AND FP. You see a lot of the 1911 platforms in 10mm but less of selection in 40.So now the cats out of the bag.I just found out why all the 40sw are still on the shelf.They have been known for several failures,Please say it isn't so.
The very reason LEE makes a die called the "Bulge Buster" Glocks are famous for the unsupported chambers. Fired factory cases have to be resized the bulge buster. As for the failed rounds destroying the pistol.......Go Figure, ITS PLASTIC .....I read this on the 40 SW
The .40 S&W has been noted in a number of cartridge case failures, particularly in older Glock pistols due to the relatively large area of unsupported case head in those barrels, given its high working pressure.[21][22] The feed ramp on the Glock .40 S&W pistols is larger than on other Glocks, which leaves the rear bottom of the case unsupported, and it is in this unsupported area that the cases fail. Most, but not all, of the failures have occurred with reloaded or remanufactured ammunition.[23] Cartridges loaded at or above the SAAMI pressure, or slightly oversized cases which fire slightly out of battery are often considered to be the cause of these failures.[23] These failures are commonly referred to as "kaBooms" or "kB!" for short.[23] While these case failures do not often injure the person holding the pistol, the venting of high pressure gas tends to eject the magazine out of the magazine well in a spectacular fashion, and usually destroys the pistol. In some cases, the barrel will also fail, blowing the top of the chamber off.
IMO.....and a lot of others not true. Check out the Rock Island (Armscor) line. I have a .38 Super and a .45acp. I shoot with guys with Colts, Kimbers, and the like. As reliable and accurate as a lot of $1000+ guns. All steel and LIFETIME WARRENTY ON the gun, reguardless of how many owners. All warrenty work done in Nevada at the Armscor US facility on their dime, shipping both ways.That's if you can afford a 1911? they run between $1200 and $3000 for a good brand of 1911.
