I've shot mine at our local shoot and move rifle match a few times and have run thru 3-4 mag in pretty short order. As far as heat goes thin shooting gloves were enough for it not to be a problem.
Some thoughts on the design and features.
The vz seems to be sensitive to muzzle devices. Some of the brakes and flash hiders I've tried worsened group sizes by a lot, I generally just run the muzzle nut.
For optics I'm using a side rail. The Czechpoint rifles are drilled and tapped for side rails and it's a dead solid way to mount an optic. RS Regulate sells a vz height riser. You can use AK height optics but they will be high. Short optics are needed as the rifle ejects straight up and using the railed optic and folding stock means you won't be able to remove the optic (the stock blocks optics from sliding off the back).
You can use the stripper clip loading feature, but it is way slower than just swapping mags.
The iron sights are easily zeroed with an AK tool. I've been using the magna-matic* for years:

BSW
*That tool ain't cheap but you'll never break it. I've twisted loose frozen AK sights that broke the standard tools. It's way better than the C clamp tools as the magna-magic doesn't spring open under pressure.
