I have a witness elite match in .40 S&W. I added it to my growing witness collection in June ( I also have a 9, 45 and 10mm ). I have not had much range time, maybe 300 rounds in 4 trips. I like it, and my buddy with a highly tuned Kimber was also impressed. It is more accurate than my other witnesses. I have had 3 warranty issues ( including a cracked slide and cracked frame on my 45 ), and EAA was slow, but I did not have to deal with Paul ( who has a reputation of being unfriendly ). You can probably find out more in the clone club on czforum.com
Pros - good single action trigger, good ergonomics if you like the CZ 75, EAA stocks some aftermarket stuff, if you are in a state that allows full capacity magazines it has more capacity that other CZ 75 type pistols.
Cons - Its a larger frame than a CZ 75, so CZ 75 mags won't work, EAA customer service could be better, holsters are hard to find ( although some SIG 229 and HK USP holsters can be made to work ), the slide is fitted, so you might not be able to swap top ends for caliber conversions ( which is possible with the regular witness )
I don't know if it is IDPA legal.
The buddy that was with me when I bought it plans on getting the 10mm version when he gets back from Bagdad, and he only handled it for 10 minutes.
