Too bad, not being able to post ANYTHING concerning a firearms modification concerning the safety. There are some modifications done that "IMPROVE" the safety's function. I'll bet some folks would like to know how to improve a weak or faulty safety. 🥺
Move the safety to the "fire" position and then use a drop of crazy glue to make sure it doesn't accidently move back to "safe"
You are correct though, that long double action trigger is all the safety it needs. I have often wondered why they put a safety on the LC9 but not the LCP.
