My combat engineered A-rated Phyton goes like this:
3G Beam lasers (long range, 6km range with 6km falloff.. lol - before they even come close, they are dead)
3G Beam lasers (long range, 6km range with 6km falloff.. )
2T Multi-Cannon turret (30% more DPS) / 3G Beam lasers (long range, 6km range with 6km falloff.. )
2T Multi-Cannon turret (30% more DPS)
2T Multi-Cannon turret (30% more DPS)
Once they arrive in range for multi, they find themselves without shields already.

If I need to hit hard and quick, I go with 3 beam. Otherwise 2 beam and 3 multi turrets.
7A enngine clean for optimized heat management
7A power distributor with charge optimization (plus 30% or so)
With 3 shield boosters (lvl 5 engineered) & death warrent scanner or 4 shield boosters if in combat zone. Shield is only lvl 3 engineered, still missing the Chinese.
Shields: 760 (870 with 4th booster) and resistance:
KIN 45%
THERM 35% (47% with 4th booster)
EXPL 50%
Supported by a class 6 shield cell bank with 5 charges and engineered for less heat usage.
Armor: 2.370 and resistance (roughly):
KIN 20%
THERM 30%
EPL 20%
Range in combat fit is around 19LY with engine lvl 3 engineered.
This ship really performs. If you complain about combat usage, give it a try. But you need engineers.
