I've had three G2Cs, which are as far as I can tell pretty much the same thing as a G3C. They have all functioned absolutely flawlessly, and I have tried every brand of 9mm ammo I could find. I also shot them dirty and tried to limp wrist them, but they ran like a top thru it all.
In fact, one of them was my primary carry gun for several months after I bought a Glock 26 that proved to be utterly unreliable and had to get the Taurus to have something to carry.
With regard to he trigger pull, it's weird to me that folks complain. It has a long take up, but is then a fairly crisp SAO trigger. It's comparable or superior to any other striker fired gun I have handled, and a million times better than a Glock.
