I just picked up my .357 sig Glock 31 last week and finally got to shoot it this week. Let me just say, BOY AM I IMPRESSED! This round screams! You guys have to understand that I never was a fan of the 9mm caliber. I always had 10mm's and 45's. But ever since the 357 sig round came out, it's been in the back of my mind, but tried for years to ignore it as another 9mm. I couldn't help but be impressed with this hot rod cartridge. Well, I finally gave in and bought it. I am blown away by it's power, speed, and accuracy. I'm a converted man. I love this gun and cartridge. WOW!
