I've handled one of these but haven't shot one yet. Its seem decently built but I'm seeing the thing go for $1100-$1300 at many NH shops. Down in the People's Commonwealth of Massachusetts I see classifieds as high as $2500. What is the big deal about this pistol and the 5.7x28 round? I know it is supposed to be a high penetration round but a little googling shows that class 3 armor stops it like every other pistol round.
