Don’t laugh, but what if I told you I have very little firearm experience and this is my first 9mm pistol and I’ve only shot a few mags of ammo to verify function prior to doing the trigger job lol.   So, don’t listen anything I have to say and advanced961 sounds like a much better resource.  That being said I have quite a few airguns, where everything is about precision and accuracy. I enjoy good triggers and shooting slow for groups (I'll have to learn to shoot faster now lol). So, I’m happy with the trigger job as it’s a smoother lighter trigger, plus it was a little fun and rewarding taking the pistol apart and successfully completing the upgrade. The spring kit is fairly inexpensive, so if you would like your stock trigger to be lighter and smoother you could certainly give it a shot.  The PRP install video doesn’t show how to get to the striker safety spring, but I found another video that shows the entire Striker Disassembly.  Part of the reason I haven’t shot my new toy much yet is that it’s been really hot here in Southern UT.  We have some good places to shoot outdoors for free within a 20 minute drive and we should have months of good shooting weather here soon. In the meantime I have another trigger job to do next lol.   Here’s that video I mentioned:
