As others have said, the aluminum grips are pretty, but the rubber grips are much more ergonomic. Like all CZs, the trigger may seem a bit gritty at first, but will smooth out after 500 rounds or so.
The CZ97's single biggest problem is that it has a soft recoil like most 9mms, and so it will not wear you out on the range. This tends to make it an ammo hog -- again, another typical problem of CZs generally (my SP-01 is particularly bad about this).
As others have said, it may also kill your enthusiasm for 1911s. I used to love 1911s, but now I look at them and say to myself, "Meh, nice WWI relic." My 1911s have now, as others have mentioned, become safe queens.
If the CZ97 has a flaw, I haven't discovered it yet. My continuing wish is that CZ would put out a 10mm version too.
