I don't have that one, though I've looked at them, but I have the 740 Slim. They're all built off of the same basic platform. I've also looked at the 24/7 Pro OSS/DS and will probably get one in .45 at some point.
I've had zero issues with the 740. I know someone who has one of the early 24/7s and zero issues there either.
For as small as the 740 is, it's a great shooter in .40. I love it. That's the gun that's usually in my pocket.
