Today I've tried a different approach with my missions Python.
It has one 3G Beam Laser, two 3T Pulse laser, one missile launcher and a mine launcher.
Mines are a very good thing, I've won several fight (or make them escape) against enemies of higher rank just running away e deploying mines.
I'm doing right now a mission to collect salvages protected by skimmers. I've tried two times, failing, because I've destroyed the canister too. First time, with the ship I trespassed the perimeter, skimmers out, then I've started to attack one of them with the beam lasers, it's gimballed, so if no target is like fixed, you need to align ship with skimmer in order to the laser hit. I've destroyed two skimmers this way, they then started to attack me, so I decided to deploy a mines over their head: skimmers destroyed, canister too, no shields and 75% of hull.
Second tim I've decided to use missiles, two of them, skimmers destroyed, canisters too.
The third time I'll try with the beam alone.
However, most important, I've had fun and maybe I found a way to make ground missions a thing to me.
An qustion, since skimmers are pretty resistance against a single beam, should I drop one pulse turret in order to have 2 beam lasers?
I have two turrets in case I'd have to fight against a more manovrable ship, but the mines trick is enough to lower shield and hurt hull, and I don't engage combat if not interdicted or for a mission.
