I'm positive you cannot buy straight from Kel TEC as far as the gun itself goes, just through dealers. As far as a bullet button I haven't a clue how those work- such BS you have to have one where you live. Go to the KTOG forums (Kel Tec owners group) under Sub2000 forum and ask. When I first bought mine I was kinda clueless about it, and became a member and learned sooo much in no time! Great bunch of guys with years of knowledge and they love their Sub2k's! Always willing to help- just follow the rules on posting, they want you to read the rules- it helps with the same questions being asked a thousand times ect... Just use the search engine and most of the time you'll find what you need, if not- just ask, they even have a section to help people find S2k's in their area. Good luck bro!
