I managed to have it working by changing some stuff.

Stock:

pawn Код:

stock GivePlayerWeaponEx(playerid, weaponid, ammo)
{
    Weapons[playerid][GetWeaponSlot(weaponid)] = weaponid;
    Ammo[playerid][GetWeaponSlot(weaponid)] += ammo;
    return GivePlayerWeapon(playerid, weaponid, ammo);
}

Check:

pawn Код:

if(GetPlayerWeapon(i) != 0 && GetPlayerAmmo(i) != 0)
            {
                new weapon = GetPlayerWeapon(i), ammo = GetPlayerAmmo(i);
                if(Weapons[i][GetWeaponSlot(weapon)] != weapon || Ammo[i][GetWeaponSlot(weapon)] < ammo)
                {
                    format(strtd,sizeof(strtd), "(SERVER): %s(%d) weap unbalance. Server-side: %s(%d), Client-side: %s(%d).", PlayerInfo[i][Name], i, WeaponName(Weapons[i][GetWeaponSlot(weapon)]), Ammo[i][GetWeaponSlot(weapon)], WeaponName(weapon), ammo);
                    SendAdminMessage(strtd, 0xD10000AA, 1);
                }
                printf("sweapon %d, weapon %d, sammo %d, ammo %d", Weapons[i][GetWeaponSlot(weapon)], weapon, Ammo[i][GetWeaponSlot(weapon)], ammo);
            }

Looks fine now. Gonna test it more to see if I'm gonna find some bugs.
