I've been a customer of FS since the mid 90's and most of my experiences with them have been positive. Most of my gun purchases from them were back before 10/98, so I was able to get my CZ 75B, SIG 228, Glock 27 and Colt Combat Target new-in-box. (oh, the good ol' days) I haven't been in there more than 2 or 3 times a year since then, but my safe has been pretty full for a long time now.
Carl is really a heck of a good guy, and even though I don't go down there very much anymore, when I do, he always greets me by name. He's given me some great deals over the years and never pressures you into a sale. The biggest complaint is that the place is always so busy nowadays that you need to elbow your way up to the counter just to get a good look at the handguns.
I've dealt with Tom before, when I went to trade-in a few pieces I didn't really care for anymore. Yes, he's a bit rough around the edges, but I look at him like the used car manager at a dealership, his JOB is to lowball you, either you bite or you don't. I did on some, but not on others. Like any other business, they need to turn a profit or they won't be there for long. I don't begrudge Tom for this because I want them to still be there next time I go back for something. Also like the car business, they probably make more selling a used gun than they do on new one.
One more thing about FS is that the inventory turns over fast in there, If you see it in the case and you want it, don't wait. I was in there last year while I was in the neighborhood and I saw a beautiful old K-22 Masterpiece. The price was very reasonable, but I really didn't need another .22 revolver. I left to go take care of my errands while I mulled it over. I decided that I wanted the K-22 and went back an hour later to get it and it was gone! When you snooze you lose.............
