I sure wish Kahr had cut some kind of deal, like Glock did with *&* over the Sigma! By now, the Colt Pocket 40 would be a reality, and I'd have options!
Brownell's has had them since December - I got three for ~$26 ea. IIRC. BTW these mags were made by Colt. While I was searching for them I called Colt directly in early December and they told me their current production run was slated for Brownells.
