I am a newbie to the Kel-Tec family. Just bought a new RDB, cocked the gun and dry fired it without a snap cap and the magazine inserted. Afterward, I was able to only pull back the operating handle about half way back, unable to completely cock the gun. The operating handle can still move forward but seemed stuck and stop at the halfway point. Also after the dry fire, I cannot insert the magazine completely in, it does not catch. I called Keltec support, they could not tell me much over the phone without seeing and inspecting the gun. So they told me to send it in. So lets not go into the debate about is it safe to dry fire or not. What I want to know is do I have a defective gun? Any recommendation to fix this w/o having to send this in unless this is a manufacture defect. I have other rifle that I could dry fire w/o seeing this problem, is this due to the bullpub design? Any help is much appreciated. Thanks.
