Hey All, every once in a while you come across that one gun that just sticks out above the others. I think I found one today it is a CCO style gun in the 10mm caliber. It has a Caspian commander length (4.25) .40 caliber slide; a Caspian (fosters) officers frame, 18lb recoil spring and standard commander guide rod. I bought this gun to resell but I had to shoot it. My favorite reload is a Nossler 135gr JHP and 9.8 gr of AA #5. I ran 100 rounds through the gun and not one hiccup. It easily shot 2 groups hand held at 25. I have always been told that a CCO style 10mm is not made because it wont be reliable not the case here though. The only negative about the whole deal is now that I have shot it I want to keep it Wanna kill these ads? We can help!
