Hey Mas, I'm sorry if this question has been asked before. I recently acquired a G21 SF and use it for both HD and also for personal protection at my business. I put in a 3.5 connector, not necessarily because I felt the trigger pull was too heavy, but because if feels better to me. Out of fear for lawyers coming after me if I ever had to use this pistol in self defense, I added an NY1 trigger spring which I've read a lot of guy's do. Would I be legally "ok" with this set-up in my pistol? Trigger pull feels about the same as factory, but still feels better than the factory set-up. My main concern is that I don't to be in a situation where I potentially have lawyers accusing me of "putting a hair trigger in my gun to make it easier to kill people". Know what I mean? Once again, sorry if this has been asked before.
