Well, I've got the CANIK55 Stingray-C, which is essentially the C-100 (well, kinda. The C-100 is a CZ75 clone, the Stingray-C is a P-01 clone in all steel, but anyhoo...).
These Turkish made CZ clones are well machined (better than the CZ's, truth be told) pistols that come at a bargain price. Fully chrome lined barrels (outside chromed, too), good slide to frame fit, good accuracy. If the C-120 exhibits the same quality as the C-100 (and the Stingray-C) you are essentially getting a slightly better produced CZ for about 2/3rds the cost, in my opinion. No support to speak of, however. Luckily almost all CZ parts seem to fit (mine is sporting the rubber CZ75 grips instead of the plastic shoes it came with, and my spare CZ75 and P-01 magazines work fine, even though the OEM mags say "Canik55 Stingray-C" on them. I called MEC-GAR and they informed me that the OEM mags were a special run, but the CZ mags were a direct substitute).
