I finally got to the range with my CS40 today and what a great little shooter this pistol is!
I put around 200 rounds of assorted ammo through it including Speer Gold Dot, Federal Hydra-Shok, Remington Golden Saber, and a bunch of FMJ. It never missed a beat and the sights were dead-on at 7 yards. Accuracy was excellent.
Though I'm not crazy about the factory Hogue grips, I shot the pistol well despite them. I have a set of Big Dog grips on order and am looking forward to their arrival.
Overall, I'm very pleased with the CS40 and am glad I bought it. I think it's a keeper!
