Call Carter and talk to them about it. They have incredible service and want you to be happy and make sure everything is right.I've had one for 5 days now. I was told that the trigger pull would be 4lbs with all three magnets installed. The most I could get was 2.6# and I wasn't even at the tip of the trigger. Took it apart to see if I could add a spring (like it's little brother, the RX1) but there is no room.
I now have a new emergency back-up.
