In January '12 I picked up an FNP40 via a gunbroker auction from Northern Firearms. They were great to deal with. No issues except it took forever for my check to clear. The gun was to me through my FFL for at least a couple of weeks before the check cleared my bank.
I called a couple of times to make sure they had made the deposit because I didn't want trouble on my end with my bank for any reason and I wanted them to be paid for the gun I bought.
Do not know why it took so long to go through, but it did and they shipped me a fine NIB handgun. I'd buy from them again and will stop in next time I drive up that way.
