I've already spent around 1500 rounds... and my M9 is just getting better... been using all types of ammo and never had any issues. I bought a 1911 at half the price of my m9, brand new but I have to spend some more money to make it work well... The Steyr is the least expensive assault pistol in the market with the utmost reliability and quality out of the box! Nothing is better! The best investment I ever made.
