The EAA/Tanfoglio Witness Elite Match is probably one of the most accurate guns made at any price, you cannot get a better trigger or more accurate gun for $500, period!
And contrary to popular belief, they're not just a CZ clone anymore, they're better! Years ago, Tanfoglio figured out how to simplify their CZ-clone design so they could manufacture them cheaper... in the process, if you agree with the sometimes "less is more" theory, they made some improvements: slide can be operated with the safety on, fewer parts, far easier/faster detail strip, better trigger bow ala 1911-style rather than CZ-75-style, better/less obtrusive firing pin block design, etc., AND at least in the SAO guns: NO TRIGGER CAMMING!
I'd put an Elite Match up against any Nighthawk, Kimber, Baer, whatever... mine positively embarrasses my Wilson Combat and Ed Brown guns, and I believe none of them will justify their price differences in competent hands at the range against the Match's based purely on how they shoot.
That said, remember that in order to get a Tanfoglio you've got to go through EAA... and that right there is the gun's weak point, as EAA's poor customer service is legendary and stupefying.
It's been mentioned that the magazines can be problematic: since that's the single piece that EAA is responsible for, I'd have to agree.
But it isn't as bad as some make it out to be...
You see, EAA imports only the "Large Frame" guns from Tanfoglio and supplies mags for them, which means as long as you go with a caliber intended to be born a "large Frame" (.45acp, .38 super, 10mm) 99.9% of the time the mags and function of the guns will be just perfect...
Now, if you go for the shorter cartridge models, 9mm or .40s&w, be prepared to put up with some feeding problems, and crummy mags, since these calibers were meant to be fired through the "Small Frame" version of the same gun, that the rest of the world outside of the USA gets to have... Since it's cheaper to only have to import, and more importantly, SUPPORT one frame size, EAA came up with using poorly designed magazines that employ "spacers" in them so the guns could be sold in 9mm and .40s&w...
Almost all of the reliability issues you will hear about will be linked to the shorter cartridge/Large Framed guns. However, most including myself have had success running the 9mm's and .40's as long as you forget about ever loading more than 10 rounds into their magazines regardless of what is their advertised capacity (loading more means NOSE-DIVE-CITY), if you reload, you can load to a longer OAL and then get away with more and will have less trouble.
In IDPA ESP division, the Elite Match in 9mm by just barely making weight is probably the heaviest gun with the best trigger out there that is still legal... unless you'd rather spend A LOT MORE on a tricked out STI/SVI that may not shoot any better.
Hope this helps.
