If I'm not mistaken, the CZ-83 is mechanically identical to the CZ-82 though in a different chambering (chambered in 9x18 rather than .380 acp).
If this is correct, the CZ-83 is going to be a rather well designed and well made pistol.
Just a thought though... you can still get a CZ-82 for as little as $159 from CDNN, or a excellent-like new specimen for $189, again from CDNN (and they're C&R eligible from most outlets).
The 9x18 is about in the same boat as the .380acp ballistically, perhaps slightly more powerful. However, unlike the .380acp, there is no apparent shortage on 9x18 fodder; it seems to be available and in-stock at just about every online vendor. Corbon loads the Powerball in this caliber, IIRC. Hornady and perhaps others load JHPs suitable for defense.
