I have run Caniks harder than most on the forum. I have 4 and 1/2 years building and shooting custom Caniks, Sars, and of course I love my Cz's. To date I have had one failure with a Canik, I called and asked for a replacement part ,instead they had me send back the pistol and sent a me new one, this was a stock stingray model. On average my caniks have 5000 to 7000 rounds thru them. I have been very satisfied with the performance to date. I have broken one older Cz as well a slide stop failed, no big deal.
