I have the Sig 22. It runs fine on just about any ammo, and has a decent trigger. The barrel seems to lockup slightly off center in the slide. It will rip out the center of the target but I have to aim about 2" left. Overall not a bad gun for a little bit of money, but irritating none the less. When it is perfectly sighted, the rear sight is actually sticking out of the dovetail a good bit.
One of my shooting buddies has a GSG and his seems to have a nicer lockup and has a similar fit finish and trigger, and no annoying alignment issue.
The one salesman at a local gunshop said straight up to stay away from the chiappa. That's all I needed to hear.
I'm a big Kimber fan, there are some guns I want to get before it, but as soon as I have a spare $750 I'm gonna get one of them, and I'm sure it will run as well as all my other Kimbers.
Just sitting here typing this post makes me wish I would have gotten the Kimber I saw at the gunshow last weekend.......
If you got the $$$$ get the Kimber.
