Yeah they are good guns and 9x18 is easy to find at gun shops, cabelas/bass pro, and online. You will not find this ammo at walmart or any big stores like that.
I don't know if the safety also acts as a decocking lever, so I would check into that. If it has no decocker, then doing it manually is a bitch and dangerous, especially for a carry gun.
They also only hold 7 rounds, You can get a compact glock in 9mm that holds a lot more.
9x18 is significantly less powerful than 9x19.
The money spent on ammo to feed this gun will probably add up quickly, I would go with a more common caliber for a carry gun...because practice is key. Unless you reload which I don't believe that you do.
My advice is to find something better suited.
