I had a SIG P232, great gun.
I traded it on an XD9 SC, not because the SIG was bad but the XD was better. More ammo, slightly better caliber...
In the time I had it I carried it a lot and shot about 1000 rounds. Only failure I had was with one type of JHPs that the gun didn't like (Silvertips IIRC), all other HPs were ok. I also used Cor-Bon Pow'R Balls in it to be extra sure that in a defense scenario it would feed.
The feed ramp on the P232 has a seam/join across it, this is what caused the FTF.
So other than a reminder to be sure that the HPs work in it ok, and that is prudent in any gun, I would say if she likes it then go for it.
The best option is a blued version, it doesn't come with the rubber Hogue grips that the Stainless does but it weighs less and costs less. You can add the Hogues yourself.
Don't buy cheap mags on eBay, get real SIG mags if you want extras, the cheap ones are hit and miss.
Takedown is as easy as it gets. Cleaning is easy, no real nightmare nooks to speak of.
You might want to look at the Bersas too, similar guns and less money again. But IMO you get what you pay for in a SIG, they're great guns.
