    I'm looking to get my first handgun soon, and I've looked around and decided on a SIG P229. Now, I'm deciding on the caliber, and I want to get it in .40SW, but I've heard that they're prone to failure. Has anyone heard anything about this?

    I'm not familar with the Sig P229, however I have several .40 pistols(SA, Glock, Kahr), none of which have had any problems.

    I have owned a number of guns in .40S&W and currently own six in that caliber. It is my preferred caliber of choice for SD open and concealed carry.

    I own one. My brother in law owns the same 229r. He is a secret service agent.

    This gun is 100% reliable and I would trust my life with nothing less.

    What failure?

    As with almost any caliber - there are folks that really like them and those that do not.

    I own a Sig P229R 40/357Sig and thanks to Sig now have10 magazines for thatlittle gem.

    The 40S&W is a good round - a compromise of a 9mm and 45ACP. Most LEO departments around the country are switching or have switched to this caliber. Sure there are more powerful rounds out there but life is full of compromises. Remember someone has to "pack it."

    http://en.wikipedia.org/wiki/.40_S%26W

    What have you heard? I have over 9,000 rounds in the last 5 years in 40 and another 4000 in 357Sig. Still going and looks great!

    I mention the357Sig since all it takes to shoot this caliber in the 40 is to change out the barrel. The frame, slide and magazines are the same.



    I got the extra magazines when I bought the Sig 556 SWAT and they gave me an in-store credit refund(they ran a special at the beginning of the year). :celebrate

    it might be that the OP is referring to the problems of 'hot' .40S&W handloads being mated with a Glock and going KABOOM!. at least that's the way i read his post. but i have been running mid range handloads thru my G22 for a few years now and have had no ill effects. as with all handloads one must be careful what one does.

    as far as the Sig P229, i personally have one in 9mm and it's a sweet little pistol. the only failure that i have had with it was mag related (ProMags). the pistol itself is reliable.

    Most of mine are .40 and its my preferred caliber. Of all the different types of pistols, I have not had a single problem with any of them (feeding, shooting, ejecting). I have never heard of any problems associated with the 40.

    .40 is an amazing caliber... there are days when I consider switching back to it. I carried .40 in a 1911 Para Ordnance for years.

    I'm really not sure about failures, either in the caliber itself or with the Sig 229 but if there were some I highly doubt it was the fault of the bullet or the gun.

    While you will always find a small percentage of manufacturing defects in any product, you should feel fairly confident going with a Sig. They do not make anything less than excellent weapons. Period.

    There is a reason the Navy uses the Sig P229 in .40 and it isn't because Sig came in with the lowest bid.

    and SEALs use its big brother the 226. Awesome pistol.

    I had a 226 but got rid of it because i got sick of being a lefty w/ a right handed pistol for carry. If i wasn't a lefty, a 229 or 226 is what i would still carry.

    I carry .40 and personally prefer it over 9mm and 45acp... but please lets not start that argument again.

    I have heard the .40+p is unstable and un regulated so Ive never touched the stuff. But both my Glock 22 and Glock 23 are running well

    I'd challenge this whole "prone to failure" line.

    Aside from it being my caliber and carry of choice, my wife selected it after firing .22's, .32's, 9's, .40's and .45's.

    It's all about what works for you, not some vague rumor mill, to determine.

    Ust picked up a Walthe P99 QA in .40S&W and couldn't love it more! Already put about 120 rounds through it, no jams, no misfeeding, and she fits like a glove. The sig 229 is a dream and a nice hefty gun too.

    I agree that this load is certainly a high pressure load to produce the numbers advertised. But if I am not mistaken SAAMI still does not recognize any +P loads for the .40S&W cartridge. If this is still the case, the manufacturer in the link has taken it upon himself to apply that designation.

    I love the round and it's my caliber of choice. I'm still relatively new to firearms ownership, but i'd say i've shot close to 15k rounds or more of various calibers with no problems with any ammo of any size.

    Sorry, I've been away for a while.

    Broondog: You were right. It looks like it was reloaded ammo, and since I'll be new in the world of firearms, I can't see myself doing that for a LONG time.

    Gentlemen, I've shot many thousands of rounds of .40S&W over the decades and have had only one catastrophic failure. The round was an early factory loaded Federal Hydroshock. The case was made too thin and it failed in my G23. Blew the magazine apart, flung off the extractor and chipped the mag catch. Hurt like hell. Federal admitted fault, recalled and redesigned the ammo with a thicker case. I put my Glock back together with a new extractor and mag catch, it's still shooting good to this day. Failures can and will happen with any ammo type.The .40S&W is still my first choice for carry.

    I owned a Glock 22 (.40 S&W) for a good while (Until I had to sell it to pay bills), It functioned and cycled perfectly. I trusted my life and the life of my family to it, this is while I was working corrections and an encounter with an ex-con not only was a real possibility, but I had run into quite a few in my outings. It happens, because there are SO MANY of them.

    If you want a +P in .40 caliber, just go get a Glock 20 or Glock 29. It's a 10mm, which is essentially a magnum loading of the .40S&W cartridge.

    Well, ACTUALLY, the 10mm came first. So technically, the .40S&W is a "10mm lite" cartridge...

    10mm fans say that the "S&W" in .40S&W stands for "Short & Weak".

    I don't mean nothin' by that... I'm just sayin'...

    When the .40S&W first hit the scene after the 1990 Shot Show as I recall, it was soon labeled the "Short and Weak". But its popularity with the police and civilian market exploded and of course, ammunition companies saw the light and created loads to fill the bill. While still not up to the power of a 10mm, and it's not likely to ever match that cartridge, it is a very well positioned SD load to consider.

    We all know how the 10mm came to be and how the .40S&W grew out of that (the Miami shootout of 1986). The 9mm also benefited from the mistakes learned in that incident and as a result, 9mm offerings are superb as well. It's sad that something like Miami had to happen to produce the spark needed for more effective loads and calibers. That tends to be the case more often than not. Hitting your target and hitting it effectively is still the best way to stop an attack. Hitting it with quality and proven SD ammo is even better.

    The 'KaBoom' or KB problem with the .40S&W was traced to a number of things:
    (I owned a G27 at the time so I was real interested.)
    1. The .40 is a high pressure round (35,000psi SAMMI max).
    2. Early Glocks for the .40 were converted 9mm and as such the feed ramp and chambers were redesigned which meant the casehead was unsupported in the chamber.
    3. If the pistol was fired in a slightly out of battery condition the resulting over pressure tended to blow out the magazine and destroy the pistol. Generally the shooter was unharmed but left with this espression: .

    Another problem is/was bullet set back. And this applies to any cartrige. Just one or two thousandths set back can increase the pressure beyond what the pistol can contain. Always check that all cartridges are within spec. before use.

    The only failure I had was with the front night sight and sig sent me a replacement but they are only warranted for 2000 rounds ...their recommendation was to have the gun serviced by them and have the adjustable combat sights fitted at the same time check the sig website for details. Never had a FTF or FTF or FTE on this weapon with thousands of rounds through it an excellent tool

    Agent, yes. Secret... not any more.
