I have 2 TS in 40. One I have over 12,000 rounds through and have only broken the fixed rear sight of all things. You can get parts from Wolverine, CZC, as well as some others in canada. The gun comes with extra slide stops and an extra extractor. A high number of production shooters in canada use CZ shadows and seem to get buy. There is a canadian warranty station so if something breaks you can get it fixed. If you already have one getting another one covers you for competition. If one breaks send it in for warranty and use the other. All guns can and will break something at some point and I dont know how speedy you could get things fixed, parts in etc no matter what platform you use.
