Can you guys and help me out with a spare parts kit to have on hand it is my first cz and I'am not sure what the common parts that break. Cz custom has a kit for 190.00 is that a good kit or do I need to build my own? Is there a book or vid on how to do a full tear down of a shadow? And my last Q is shooting uspsa or idpa if a part breaks in your gun do you guys try to fix it or do you have a back up gun? Trying to figure out what I need to do for uspsa matches
