Tanfos may be durable today but because there was this epidemic failure in QC 5-6 years ago and the local market is small Tanfo never got back to the game in FInland. Their prices are +50% more than comparable CZ´s and because ther lousy QC reputation very seldom any serious competitor buys new Tanfos here anymore. If you buy value for your money you buy CZ here. If you buy ultimate durability and customability and want to compete on the top 10 in Standard or Open you buy a customized STI. Tanfos lost the game and due to our quite strict gun laws nobody wants to buy a lemon that can not be fixed.
Those still shooting .40 kal Tanfos do tell me that their gun needs to be rebuilt (mainly triggers,sights and magazines) more or less every 5000 rounds. Maybe they load too heavy loads or do not know what they are doing but have heard the same story from several reputable shooters having shot Tanfos for many years. They still shoot Tanfos because it fits their hands well and the trigger can be prepped very well. This is a bit like Porsche vs Ferrari for daily use. Both go fast but with Porsche (CZ) you can do your daily stuff without having a personal mechanic with you at all times. With Ferrari (Tanfoglio) you have to hire a personal mechanic (Eric Grauffel) to keep your car (gun) running proeprly.
If your Tanfo works enjoy it then do not worry about it. Maybe they fixed the issues.
