I think CZ has price going for them for parts. Patriot Defense seems to be as responsive as Canjun Gun Works.
Tanfoglio has going for it a drop safety block that the CZs don't have.
While the trigger is better on the CZ, absolutely no difference to me in accuracy in my Shadow 2s and my Stock Master (a Stock III frame, updated slide).
Shadow frame is rounded more.
Tanfoglio trigger is super curved. I hated it in dry fire, but on live it's great.
Hello set screw in the Tanfoglio (stock):
The Tanfoglio frame is way more comfortable at then tang. I have small hands, so I know others know what I mean that the Shadow frame is too narrow right at the tang and your web doesn't actually contact the frame at the undercut.
CZ moved their new Tactical Sport 2 Orange to a bull barrel, something that is stock on all the Tanfoglio Defiant frames.
Tanfoglio comes chromed, a $500 job Cajun or Fords on a full Shadow. I think hard chrome is the best finish a gun can have.
You can not like it, but I think the internet talk is way over stated on quality differences. Different, but on target, I can't tell a difference. I agree the Shadow is kinda better, but on target, I don't see it.
That said, the Tanfoglio and CZ are just similar. Like the OP is saying, there aren't many terribly "new."
If you can hold first, an interesting one is the pardini GT9. I think hold it first though. It's boxy. Mag prices are just stupid insanity.
