Interesting thread. To me, several of these handguns are pushing the limits for pocket gun ... but perhaps we're including cargo pants pockets.
The older (almost antique) weapons are fascinating !
My wife carries a Solo. When we first got it home it would randomly drop the mag when being fired. This happened when both of us fired it, and a couple of other people too, so it went back to Kimber. Kimber fixed it so well that it's a little difficult to drop the mag now. Even with that, it has always been reliable when the mag stayed in, no failures to fire or eject with any type of ammo. She carries 147gr HST in it, but it's handled somewhere north of 500 rounds of 115gr (mostly WWB) with no issues.
