I have one, but it's the 24/7 DAO and not the 24/7Pro DA/SA version. If you're getting one, definately go for the Pro. It has a unique trigger that automatically reverts to DA in the even of a misfire.
I can't really offer a real review, but I can say I have no complaints. Other than the trigger pull being very very long on the DAO, but that helps in trigger control I think. It's quite a small restricted auto, one of the smallest I believe. Not made for big mits.
The grip is absolutely amazing (Taurus rubber ribbed) but tends to get all sorts of dirt and s**t in between the layers of rubber and it's very hard to clean if you were to ever drop it in dirt etc.
Very solid, very well built and the craftsmanship is A+++ I also think it's one of the best looking pistols out there.
Having said that, I've never been able to shoot it well. I've let many new shooters use it, and they've grouped quite tight with it, but for some reason I always seem to be way off target even at close range. I never could dial it in, even when I bench-rested it.
I loved the thing to death .....until I got my G17

Since then the 24/7 has been collecting dust. It really is a great gun; but between the two there really is
no comparison.
I only have two pics, but they at least give you a size comparison to a P22 (which is TINY) and a G17;
