One per thousand is a 0.1% failure rate, and not good enough.

Every 1911 I've ever had has gone past that. I don't shoot as much as I'd like, but over the years the reliability history builds up.

My Government Model was horrible when I first got it back in the Carter administration. One trip to a good gunsmith cured everything.

After having owned it 40+ years, the extractor broke about a year ago. As best I can remember that's the first malfunction I saw, post gunsmith.

There are definitely other guns than 1911's, though, and the 1911 is an old design - but I don't feel unarmed with one.

The thing is that having to take a gun to a gunsmith to make it work isn't buying a reliable gun. Over and over again, I hear people defend 1911s by saying once they fixed this or fixed that, or went to mag A or mag B, They haven't had a problem with it. If you have to fix a gun right out of the box statistically it's not a reliable gun. You are correct. though you can get a reliable 1911, it's just that there are reliability issues inherent with the 100-year-old platform. There are some guns that can be trusted after shooting a box of ammo through it and some that are need a lot more.

Strange since he was such a 1911 fanatic. Sort of blows holes in some people's arguments that 1911s are inherently unreliable, doesn't it?

1 failure in a thousand is pretty lousy repeatability as far as I'm concerned. But Cooper had to settle for that to compensate for his beloved 1911. Also Cooper wasn't dealing with things like subcompacts, Kimber and Taurus.Yeah, overall its fair to say that some 1911s might reach the 1 per 1000 failure rate. Some people even believe that this is good enough.

MOST of the Magtech I've fired has been hardball, with the exception of some .45 ACP and .44 Magnum JHPs. That said, I haven't shot any Magtech in a while, so maybe their QC has degraded or something? I don't currently have any on hand.

What I think is going on is that she might be limp wristing and a lower pressures caused by 115 gr. and possibly the Magtech ammo are aggravating the situation. I know little about Magtech, but it being an economy brand, and Sig admiting that there have been problems reported with it. I don't know much about the Sig she is using either, but some guns might like a little more oomf to cause a complete cycle. The defensive loads she is using is probably power enough.

I figure that most 9mm handguns were designed for 124 gr as a median. So that is what I shoot. Heavier subsonic have their olaces .. 115 might have better penetration ... I always though 115 was lighter than the optimal especially for target loads. Having said all this, I have shot a whole lot of 115 Winchester white box and cheap russian crap, and I have never had an issue with any of my guns, and I wouldn't hessitate to use 115 gr defensive rounds, if there wasn't anything affordable available.

Is this Magtech Ammo defensive ammo? I have been avoiding 115 gr ammo in my 9mm These days my range ammo is 124 gr NATO Winchester white box. I just doesn't feel the same or shoot the same as defensive ammo. I can't afford to practice exclusively with defensive ammo.

Put aside the Magtech for now.
Pick up a few boxes box of Winchester White Box NATO.
Let your wife shoot through these and see if she has any issues. If she has no issues after shooting a few boxes of this ammo we can safely blame the Magtech Ammo.
If Sig claims there is a problem with Magtech I wouldn't find it hard to blame the ammo.
Probably not a good idea to rely on discount brands of Ammo for self defense .. To be safe I would use what the LEO community uses.
