As much as I am SIG fan, I carry a Kahr pm40 or 45 the most due to their size and ease of concealment. Both of those little guns are extremely popular and S&W WILL enter the single stack 45 sub compact (shield) market just as springfield has recently. Its really a no brainer. I REALLY hope the can the goofy safety though. I realize its a requirement for the communist states but here's to hoping that they start the 45 shield without it!
