The Tanfoglio/EAA Witness guns are a good buy.
While not up to the quality of the CZ originals, they offer all the benefits of the CZ design at a cheaper price.
While CZ uses forged and milled slides and frames, the EAA guns use cast, so the lower price.
However, the development of the CZ design is actually being driven by Tanfoglio. While CZ was still offering only .9mm guns, they were making the .41 A&E, and then .38 Super, 10MM, 40 S&W, .45 ACP, and .22LR.
CZ still uses the original profile trigger, placed very far in the front of the trigger, while guard, while EAA has reshaped theirs to put the trigger further back in the back of the guard, greatly reducing the trigger reach. For some reason CZ won't make this basic change, so their guns have VERY long trigger reaches.
Tanfoglio was first with a Commander style rounded hammer, a better, redesigned safety, and a stainless gun, (now discontinued).
So, if you want a CZ-type gun with good quality, reliability, and accuracy the EAA is the way to go.
