Yep, you guessed it;I lost it. This was the third time disassembling my gun (once before I fired it, then after the first 100 rounds and now after the second 100 rounds). I knew the ejector is loose and can fall out but I still forgot about it and used brake cleaner and then compressed air to clean the frame. To make matters worse; I did the cleaning over the grass instead of over the concrete drive so it is gone forever!! > :'( This is not my only gun but it is the only one with a part that can just fall out. I know, I know, that's no excuse. :-[ Now the good news; I called Kel-Tec and was informed that they would send me another at no charge. No charge for the part and no charge for shipping. Are they a great company.
