I would like to vote in your poll but it seems that you have left out a couple of the more popular conceal carry manufactures.
Over the years I have carry every manufacture listed (plus some) except Taurus and Glock and found them lacking for what I wanted in a conceal carry. Probably the closes that I ever came to my idea carry of those listed was when I carried a S&W 3913 but still wasn't happy with the size of the gun to caliber. So I opted for Walther PPK/s in a caliber that I felt uncomfortable with and question whether or not it was adequate for the task that I was asking it to do, plus was finicky on what it would digest. I was about to go back to the Smith when Kahr Arms came on the scene with their new conceal carry, the K9.
The Kahr drew my interest as it was approximately the same size as the PPK/s but chamber/rated for the more potent +P 9mm. In addition I like the inherit simplicity designed into the pistol of a true DAO "without" the need for additional safeties (like Springfield's XD). Needless to say, seeing the possibility of the pistol I didn't hesitate to purchase one while they were still reasonable (anyone remember what you could buy a Glock for before they became popular?) and wasn't disappointed that I did. But as good as the K9 was, there was some issues that I had with it. First was that Kahr didn't seem to radius the edges on the early guns which I promptly cut the back of my index finger on the edge of the trigger guard. Next was for such a small pistol it certainly weighed alot and last was the sights. While I like the Dot/Post configuration the rear sights on the gun ate up a number of liners on different jackets even with protectors sowed in. Due to these few thing I sent the pistol to a gunsmith friend of mine to correct these problems. Several months later I received a custom Kahr with meltdown radius on all edges, lightening cuts on the slide, Novak combat sights, 30 lpi checkering on the front strap of the frame and the butt point of the Hogue wood grips was knock-off and rounded to lower the pistol signature. I thought I had the best conceal carry ever until I walk into the same gun store that I purchase the K9 and spotted the new (at the time) TP9 by Kahr.
While I really liked my K9 especially after having the work done that I did. When I compared it to the TP9 I found it lacking. The TP9 was lighter even though the K9 had been lighten. I prefer the longer sight radius of a 4" vs. 3-1/2" and the fact that it was Polymer and Stainless where the K9 was still gun steel (I believe they're all stainless now?) and require constant rust prevention especially on a humid days. In addition the TP9 was slimmer in the grip due to no grip panels (lowering it's signature) the grip was textured all the way around and all the edges were radius. In my way of thinking there was no comparison between the two, the TP9 (IMO) was the carry conceal answer to Nirvana.
Since that day that I trade my K9 for the TP9 I've had no regrets and haven't carried anything else as my daily carry. There are time when I've entered areas to work, where known problems exist where I might trade it out for my BHP just on the firepower standpoint. But to just walk down the street or shopping the TP9 is it, of course with a couple of trusty blades backup .
