Electrical Help for a Push-pull solenoid

It was just a price matter. The P channel was cheaper.

Then you are not looking at mosfets with similar specifications. N-channel mosfets are generally cheaper than similar P-channel mosfets.

So maybe i'm looking wrong, i pay 16€ shipped for a pack of 100 p-mosfets like those with -5v Vgs , 25amp, 30volt. I pay almost the double for thre N kind with same specifics.

I'm looking for Vgs 5v , not more not less. Almost 15amp , and obv at least 12v am i looking wrong? Could someone tell me the near-right specs? The resistence of the coil is 7ohm

Noob question alert:
If a Vgs mosfet is rated Vgs = (+/-) 10 , it means it will be activated by the range -10 , 0 / 0, +10 , or it need the min and max value of -10 / +10?
