I got this part just for the looks. I know its supposed to reduce lock up time, but really how much? The main reason to buy this is the looks, and it has that! It is pretty easy to put in provided you have the dogbone pin on your hammer spring. If not then you may have to punch it out, and while you are there replace it with a dogbone style. Other than that it pops in real easy and has a killer look. Follow the video and its is just that easy.
