Only had one situation close to this. Made a deal with someone for an off-list handgun. On my way to the meet, he calls my cell and says he just realized he had hit his 4 transfer limit. so he can’t do the deal. I don’t try to convince him that doing 5 transfers in one year probably won’t even get him a letter; just turned around and went home. Later that day he called to say he found an FFL that would do it as a frame transfer and we went ahead and did the transfer the next day. He paid the transfer fee. Now that was an upright guy.
