I have been a Glock shooter for a long time. I purchased a CZ and I love how the gun feells and shoots. I am looking to add a Tanfoglio to my collection. Based on reading the many posts it seems the Stock 2 is the preferred gun for USPSA. The problem is it seems the Stock 2 is hard to find. I have been able to find a Stock 3. I have also seen the Stock 2 Xtreme and the Stock 3 Xtreme for sale. I have read the Stock 3 has a problem with the finish coming off and then rusting. My question of the 3 Guns (Stock 3, Stock 2 Xtreme and Stock 3 Xtreme) which one would you advise to purchase. Looking for 9mm to be used in USPSA Production.
