I bought this Kel Tec Sub 2000 9mm Glock (Gen 2) on Monday 10-9-17 at night from a guy on Arms List. I took it out after work on Tuesday 10-10-17 to try it out. Cleaned it and all, it looked good. I was using the factory magazine with Winchester ammo. First several shots were great, I was getting used to putting my face hard against the stock to be able to aim. So, I was hitting good that way, so I thought I would finish the last eight or so rounds by rapid firing them. I held the gun a bit lower and opened up. A few shots into this exercise, had a louder than normal boom, my left arm starts hurting real bad. I look down and the gun barrel it split open, my left wrist is bleeding, and I am dumb founded as to why this happened. This seems like a fairly new gun in good shape. I called Kel Tec, they guy I talked to was very casual about it like having a gun blow up in your hands is an every day occurrence. He tells me to box it up and send it to them and they will let me know what it will cost to fix it. I guess I am going to do that, I took a lot of pictures of it as well. I wish I could have found a new one to purchase so I would have the lifetime warranty. As it is, I bet they say it is not under warranty or something like that, and it will cost me just as much again to get this gun fixed. If they charge me, I am going to insist that they send me back my barrel that is split open so I can show to everybody as often as possible. I did not know that this gun had a history of blowing up or I would maybe have looked at a different carbine. Just thought I would put this out there for everybody that is thinking about getting this gun. I will attach a picture if it lets me.
