On Top:

pawn Код:

new WeapPU

in OnGameModeInit:

pawn Код:

WeapPu = CreatePickup(ModelID, PickupType, X, Y, Z);

Create new public if you don't have one:

pawn Код:

public OnPlayerPickUpPickup(playerid, pickupid)
{
   if(pickupid == WeapPu)
      {
          GivePlayerWeapon(playerid, WeaponID, Ammo);
      }
   return 1;
}

Pos, if something is wrong, or/and you have questions.
