My brother in law purchased one a month ago for around 300 bucks. He also relayed that it was designed by one of the kel-tec guys. He brought it over and I helped him clean it before shooting it for the first time. Cant remember much about the design/mechanics of it but I remember thinking it had a wimpy recoil assembly. the spring quality was nothing to write home about. I bet its go some kick to it because of that. I asked him if he could get a better recoil assembly for it and he said that because is the first design they have put out that there are not yet upgradable parts for i yet. so.. its light weight. its small. when I take him to the range next we'll see how it performs. hope that helps.
Almost got one yesterday. Decided to do more research. Found that their customer service is top notch and fast. Seem to be a well built and thought out firearm. The low price I account to being a new compony with low overhead and the desire to sell lots of guns. Low price doesnt mean "cheap". Plus thier made in the usa.
