When parking the vehicle put it in neutral first then use the handbrake, then in one motion shift into park making sure you're not pausing in any other position on the way.
I think (anecdotally) what is currently happening, because you're in gear and foot on the brake there's some load on the trans when you put it in P, then pulling the handbrake keeps that tension/load. Then you go to leave the next time and shifting from park to R you're unloading it and it feels like a harsh shudder/shunt.
give it a try and see what the result is.
Another point to remember is weight on the parking pawl. This is similar to above but in a different area in the trans. If when you put it in P and the vehicle rolls back or forward against the parking pawl (which essentially holds it on the incline/decline) that will create a lot of load on it and when shifting out of P it shudders/shunts.
Change of behaviour will prevent it:
hold the vehicle by the brake pedal and shift into N
apply the handbrake so it holds the vehicle and won't roll
release the brake pedal
then shift into P
This will ensure there's no load on the trans at all and the brakes are holding the vehicle, so when you next go to shift it's all butter and cream smooth.
