I have never had a problem. Every KaBoom I have heard of in 40S&W was either a reloaded round or a factory defect. An improperly loaded round can blow up in any gun. It just seems worse in 40S&W because it is already a high pressure round. If you stick with factory ammo with good quality control, you shouldn't ever have a problem.
My CZ 75B in .40 has ALMOST a fully supported chamber. I don't worry one bit about KB's. On top of that, many of the people I know who shoot GSSF or IPSC at the Richmond Rod & Gun Club reload .40's and use them in their personal Glocks. No problems so far (out of the thousands of rounds they have reloaded). If you use a little common sense (check the brass before reloading for example), the chance of a KB is very slim. Don't sweat it. 
I shoot Glocks, CZ40, Kahr 40, Browning High-Power, FN49, and TZ75 in this caliber. It is a good caliber if you don't push your reloads, watch the range brass, and monitor your use of lead bullets. According to Wayne Novak the BHP is a great weapon for this caliber. Regards, Richard
kidcolt, apparently you have a .357 barrel, since you can't drop a .40 barrel into the 9mm P229. I don't blame you for wanting to save a few bucks on ammo! I carry a P229/.40 and shoot either 165 or 180 grain loads. I'm unaware of any P229 KB's with .40 ammo, although I know of one KB in a SIG 2340 which occurred with 180 grain reloads.
The problem with 180 grain reloads may be related to the reduced case volume which results when the longer 180 grain bullets are seated deeply enough to meet the O.A.L. limit. Since chamber pressures are already high (33,000 to 35,000), there is little room for error, either in over-charging or improper seating/crimping.

are 180 grains behind all the kabooms
as best as i can rember i have never heard of a kaboom with ligher bullets.i would be using reloads.i have been doing it for over 20 plus years without a kaboom wont to keep it that way,thanks,keith

If you are using reloads, the advantage of a lighter bullet is because you will most likely have a shorter bullet. This means that with the same OAL, you have more space in the casing and therefore less pressure.
It ain't the round!
The fault, dear friends, lies not with the cartridge, but with ourselves!
The problem is with reloads, and the guns in which they are fired. According to an article in Combat Handguns which I read a while back, most KaBooms can be traced to collapsed cartridges in reloads. The reloads DID NOT have enough neck tension on the bullet, and as a result, the bullet is forced back into the case during the semi-auto loading cycle. This causes pressures, in a round that is already on the edge, to skyrocket!
How to prevent it? When you flair the case mouth during reloading, you are also expanding the case neck. This expansion decreases neck tension and makes the bullet more suseptable to bullet set back. One solution is to turn down the neck expander portion of the plug to eliminate the unnecessary expansion. This will increase neck tension. Another solution is to do as I do. I DO NOT flair the case neck at all! I leave the case as resized and chamfer the case mouth with a Bonanza tool from Sinclair. I then seat the bullet in the unexpanded case and DO NOT CRIMP!
NO CRIMP? Yep, no crimp! The crimp DOES NOT increase neck tension, it is to remove case mouth flair. In fact, crimping can actually REDUCE neck tension! I discovered this once when I over crimped, using a taper crimp die, some 9mm. After crimping, the bullets, which HAD been held firmly in the case, could now be easily turned in the case! So, I DON'T CRIMP! And I have never experienced bullet setback in one of my reloads.
Now, as to the guns. The problem with KBs in Glocks has been much discussed in the National Range Officer's Institute of the United States Practical Shooting Association. The conclusion is that Glocks are more suseptable to bullet set back due to their feed ramp geometry. Apparently the slope of the ramp is such that it puts undue reaward force on the bullet, making improperly reloaded bullets more suseptable to bullet set back. The result, more Glock KBs.
Glock recognizes the problem and FORBIDS reloads in their guns. Many shooters, however, use reloads in their Glocks with NO PROBLEMS. How is this? Well, I suspect that they know how to assemble a proper reload, with maximum neck tension!

i dont flair the case for the 357 sig either dont even chamfer it.i would if i were not using 124 rainer's.over crimping will make the bullet lose you right about that for sure.sounds like its a people problem not a 4 S&W problem.still i might get a baby eagle for peace of mind.its cheaper to blow a baby eagle or an EAA than SIG,thanks,keith

can i convert my baby eagle to 40 S&W its a 9mm right now,its the full size one.
I've been shooting and reloading the .40 for 3 years now. I've experienced split cases, but no kB's. Of course I've had split cases in 9mm also.
On my reloads I apply a light taper crimp, which holds the bullet nice and snug.
I don't think there is any more of a threat of a kB from a .40 than that of any other cartridge. However, the Glock may be a little more sensitive becasue of its rifling, which seems to perpetuate lead build up (if shooting lead) which can cause higher pressures and slightly larger chamber that allows for more reliable feeding.
But if your carefull, I don't think you'll have a problem

I've shot over 8 thousand rounds through my 3 .40sw GLOCKS all factory ammo.No lead,no reloads.and it looks like all 3 are shooting as well as they did when I first got them.Sure there is surface wear,(blued to silver) but thats common with number of rounds through it.Nice tight 3 inch groups,no problem here.SAFE-SHOOTING!
