I run a standard TS for 3 gun and its a great gun for it. The only things I've done to it are installed a CGW hammer, lighter recoil spring, lok thin boggie grips and a TSO magwell. The gun just runs and I've had zero issues running it all year. My only issue is the lack of kydex holster options for it, I run a blade tech classic owb, but wish there were more options and a decent retention holster for it.
