You should change to decocker. The Decocker on the P-07 works a lot better than the safety does. The safety comes from the factory with an easily broken spring loaded plastic detent piece that gets lost sooner or later.
The safety never worked well, but the Decocker works great, even better than on my other Decocker pistols (3 Bersas).
After my experience with it, I wouldn't advise anyone to use a P-07/09 with the Safety lever. Switch to decocker and have peace of mind and sure function. Since the pistol has a firing pin block and the safety is unreliable--there's really no good reason to keep the Safety lever and its spring loaded detent plastic piece that is not reliable.
If you want to change back to decocker, JOE has a video to show how to do it. Without the video, it would be very frustrating.
