I could talk about CZ's all damn nite.
Any of the Shadow variants will do the job. There's a lot of choices in them now, mostly sight options and finish.
An adjustable rear sight would be nice.
If I were buying a 2nd CZ today (for a back up competition gun) I'd get a 75 Shadow because it'd be IDPA legal (always bugged me that the Shadow was too good to be legal in IDPA) The 75 Shadow has a short dustcover...the regular Shadow has a full dust cover.
They need some tuning, there's a few tricks to learn along the way.
Demand for the CZ is going to go up if the Production rule changes come to be. The days of seeing a bargain in the classifieds are over.
Buy one from CZ Custom or Matt Mink. They both do awesome work. Matts will have a lighter trigger. I once had a 75SA from Matt...the trigger was telepathic, best trigger I've ever felt on any gun.
The Shadow is DA/SA, mine is 5lbs on the DA and just under 2lbs in SA with no 'wall' I've forgotten the numbers, but I shoot my fastest splits with my Shadow, even faster than a rimfire. Its not all trigger of course, the gun is heavier than my Limited gun, with a fairly light slide, shooting 132pf loads thru a 10lb recoil spring it kicks just a little more than an airsoft gun;-)
CZ's in general, and the Shadow in particular are crazy accurate.
