I bought a new T3 in 300wsm this year and would like to lighten the trigger a little. It shows how to do it in the manual but they say that it should not be done and that you must send it to the factory to get the safety reset for some reason. Are they just doing this to cover the themselves for the liability purposes or is this for real. So can I do it myself or take it to a gunsmith. Thanks in advance. Dev
