No trigger pin - they use a rolled up sheet of metal
Ok I didn't want to pay $40 for a trigger, but I did and I don't regret it. It came in a nice package with clear instructions which is always a good thing. The sheet of metal that is in place of a solid pin could cause problems if you have to take the trigger on and off. The trigger can be adjusted for flipped or non-flipped switches, so you don't need to flip your switch. The reason I put plastic as a weakness is that you can't use any type of thread locker once you adjust your trigger settings, so you may need to readjust every once in a while. I like how you can adjust the magnet on the trigger. It's really light and I can set my trigger very tight with out bouncing. I switched out the stock trigger screws only because the way I set my trigger I needed the longer screws. The trigger pull is very smooth and light. It says that you don't need the magnet in order to use the trigger, but I feel you might get more bounce that way and I don't want to get DQ'd.
This is a great trigger for the price. I was looking into getting the CP but I couldn't resist the lighter composite trigger. The pictures on their website doesn't do them justice..they look a lot better in person.
