You metioned a 9mm Kel-Tec, thats what i carry mostly, small, very lightweight, high capacity (if you need more than 10+1 the take ANY s&w 59 sereis mags, i'v got a 30 rounder just for fun cost $15 bucks at a gun show.) shoots about 4" groups at 15 yards, and i'd trust my life to it to shoot everytime i pull the trigger. You can get factory night sights now too. I usually just carry it in the wasteband, its so light it hardly ever moves. Only downside to you is no saftey whatsoever, except the 9.5 Lb. trigger. It dosent bother me, i just don't keep a round in the chamber, i just pratice loading in my pull. I saw you mention that about the glock though. I also have the .40 caliber, just as good, just havent broken it in to carry yet, not much more recoil either, really none that i notice between the two. For $200-$250 best guns in the world in my opinoin. Try to find someone that has one so you can see how it shoots.
