Concerning the original question, if I assume for concealed carry someone is looking for a good quality, accurate, well made, concealable, pistol ... I've compiled the rating/reviews of over 400 pistols (no revolvers) into a searchable database and searched (just a guess what might be good as CC while detecting) using these keywords: "small", "High-rating", "light", "Accurate", "less recoil", "Cheap pistol" and here are the results (for entertainment purposes):

If you list the traits you are looking for (up to 10) I can see what pops up. Pistol filtering is limited to the following keywords: Small, Full-sized, Light, Heavy, Accurate, Cheap ammo, Cheap pistol, High-rating, Less Recoil, High-Cap, DA, SA, DA/SA and/or a particular caliber(s) like 40SW, 45ACP, 9mm, 50GI, .357Sig, 10mm). Because I'm not interested in less powerful pistols than 9mm, results typically don't include smaller calibers since they aren't in the database (in this case a few .22s showed up because they are highly rated and interesting at the time).
