It sounds like for you, C/L may be tough and the decocker better. it IS a modern DA/SA gun. Having that option is good, and I will say that the slide release is EASIER to use with the safety, and some folks IF well trained enjoy a consistent trigger pull with the manual safety.
Keep in mind that I have gone over to DA/SA for carry purposes. I also like to decock with my support hand. The P07 is pretty easy, but even easier to decock with my support hand - which then also allows you to keep your strong hand in perfect alignment ready to engage the whole time you decock, check your LOS, and reholster. I think decocking with the firing hand is weaker, and more vulnerable, and reholstering should be a conscious two handed operation anyway.
This is also why I think decocking a gun like the P07 even with a manual safety can be done safely and easily with the support hand thumb blocking the hammer. Not pinching like a brain dead gun reviewer. But, BACK to the OP - some have trouble getting the safety to release with small to medium thumb length.
You will THEN need DA and DA/SA practice, plus much shooting and polishing and likely the CGW extended FP and 15 LB mainspring.
