Yes, it’s a take it out/ put it in process to ensure proper figment and operation.
Just go with the RHK race hammer kit. It’s a lot easier to install and more forgiving compared to just using the 10035 hammer. The kit comes with the competition hammer and adjustable sear. The adjustable sear has a set screw on it for adjustment. Once you get it adjusted properly, make sure you put a dab of the red loctite that comes with the kit.
If you run into any problems, just give CGW a call and they’ll help you out. They have a great customer service.
