TKG, greetings! That is a very effective and often overlooked cartridge and handgun combo for varmint and small game.
I knew of a fellow that put an adjustable rear sight, custom grips, and some other modifications into one and it turned out to be a very effective small game hunting handgun [not that they are bad in stock form either
]. I think he got most of his parts and technical data from Makarov.com.
Interesting factoid of firearms history you probably already know but is worth repeating: before the fall of the Berlin wall, those rolling block CZ pistols like yours commanded upwards of $1300.00-$1500.00 from collectors!
I am thinking of having a Contender barrel made in that chambering, maybe a 10"-12" open sighted small game getter. With the wide variety of 30 caliber bullets available, it might just be a great deal of fun to tinker with :-)
