And that, my friends, is why the 22 TCM is the way to go... Equal or better ballistics to the FiveSeven and you can swap it to a 9mm in a pinch. And 22 TCM is roughly half the price.
This is why I could never bring myself to buy a five-seven. Interesting design and a great pistol by all accounts, but ammo is the problem. During good times it was fairly readily available, but in lean times....not so much.
