This is the latest incarnation of a gun that borrows attributes from many designs. Overall, it is very Sig-like. Frame size is roughly equivalent to the 226 with a 229 upper on it. Meaning full service size with about an inch shorter barrel. The first time I remember see this, it was a Yugoslavian import (I forget what it was called). Later it was brought in as the CZ-99 but was not, from what I've able to gather, a real CZ and was not brought in by CZUSA. A local shop still has a brand new one in the case (I'd imagine it's about 5 years old now). Then it was brought in as the Israeli Golan. I had one of these in .40. Accurate. Only reliable with full power loads though. Pluses were an ambidextrous decocker and mag release (similar in design to the XD/HS2000 series). Later it was brought in as the TZ series guns in .40 and 9mm. Charles Daly is merely the latest incarnation. And, BTW, it has been discontinued. That's why CDNN is closing them out. This particular variant has some sort of indicator set in one of the grip screws that has been problematic (I believe it's a loaded magazine indicator). My impression is it's a good $200 gun. Much more than that is not a good idea b/c support for this design just isn't there. Something breaks, you'll have a hard time getting it serviced/parts.
BTW, a little unsolicted advice: Get the Stoeger Cougar (which is the same as the Beretta Cougar) CDNN has for $299. Parts are readily available as are magazines and the gun is still in production (albeit made in Turkey). Much better deal.
