If you get any of these, especially the Keltec PF9, or a keltec P11, be sure to take it out and shoot it right away. They like to break fresh out the box. No point on carrying a gun around if the firing pin is going to break on the first shot. Keltec will fix any issues you have pretty quickly, but you have to shoot the gun to find the issues.
I'm not sure about H&K or S&W but there's a thread on here that talks about bad customer service. If you're shopping in the $250 range it's probably a good idea to visit that thread to know who to stay away from. Because whatever you buy, you will almost definitely be using customer service at first.
