I sold some Glock parts to a customer who contacted me concerning the parts I had listed on Glocktalk and he sent me a personal check as payment. I do not have his Glocktalk user name as he contacted me directly via my e-mail. I deposited the check on July 10th and it came back as insufficient funds. I have attempted to contact him in regards to this matter and he has still not made the check good and will not return any of my e-mails. I have waited till now to post this in an attempt to give him every opportunity to return my messages and make the check good and still nothing. Hopefully this notice will keep anyone else from conducting business with this person and getting burned. Since I don't have his Glocktalk user name, his name is listed below. William H. Cohen I will update this post if he decides to make the worthless check good.
