I recently got the opportunity to shoot a 9x25mm custom STI pistol. This gun is crazy! The flames from this gun are almost as big as the Desert Eagle 50AE that I posted earlier this year. But, the recoil of this gun is very manageable. I was surprised at how controllable this gun was to shoot. And the cool thing about this particular 9x25 Dillon, is that it was built with a second upper that allows you to shoot 40S&W.
