Is it worth it? Absolutely. Super crisp and light trigger, shorter reset, hammer and trigger just feel much more high end. The lighter decocker spring makes a noticeable difference in decocking too.
Is it worth it to DIY? In my opinion, no. It was a total pain and the whole time I was worried I would bleep something up. It turned out fine but CGW really doesn’t charge that much for the install. I would let the pros handle it next time. I had a lot of fun installing an M carbo kit and polishing my P09, but the CGW kit is straight up tedious to DIY.
