Things to do once you have a CZ
I'm not going to post a How-to, more a "what to get done".
With a CZ 75 you will probably want the mod that is standard on the 85, drop free magazine brake.
An owner can order the 85 magazine brake or flatten his own, there are other places on the web to tell you how to do that.
The other thing to do is have a gunsmith smooth the trigger.
Stock triggers on ALL handguns below $1000 in this country could stand improvement and stock CZ triggers tend to be their biggest percieved flaw.
You buy a great gun, make it greater still by having someone competent do the trigger work. If that's you, okay, go for it. If you are me you take it to the gunsmith and pay his price and get it done right.
Some people have an attitude about gunsmiths (and very likely some gunsmiths have an attitude) but my gunsmith takes my money and gives me service with a smile. He backs up his work by working more to fix things if he didn't get it right, for free.
If I could get a politician to do that I'd be a very happy man, indeed.
