The Kahr pictured is a good weapon. I'm an avid gun collector and sport shooter. My personal favorites are Walthers (own both a ppk, and p99).
A used .38 S&W is both affordable, and reliable.
Glocks are reliable, but Ive shot them, the mag and slide releases are stiff and sharp. Not user friendly (for a sport shooter, I suppose in combat it doesnt really matter)
Sigs, HK's, and Walthers are all expensive, but fit better in the hand, and are overall a bit more polished in the "user friendly" dept.
All go bang, doesnt really matter what you choose, as long as you stay away from these...
>Bryco, or Jennings... The definition of a Saturday night Special. Never waste money on them
>Taurus, although I've heard good things about their newer guns, I dont trust them. Had a Taurus revolver (one with that little hex key hammer lock thing) jam on me. I guess the recoil set the lock, and since I lost the key I never could fire it again (gave it to a friend)
>Kel-Tec and Ruger, thats about as cheap as I'd go. I havent heard anything bad about them, but Ive fired them, they feel cheap. I'd buy a used s&w before I bought one of these.
>Beretta, is supposedly great, I've only ever owned one Beretta. A little .25 cal Bobcat. Shit was shit. The tip up barrel switch broke after 2 range sessions. I bought it brand new. And its the only gun in my entire life I've had a bullet fail to leave the barrel. Was probably a problem with the ammo, but I wont trust a Beretta ever again.
