They advertise being the largest gun store in the world.
That can certainly be debated. We have a store in Florida called AAA pawn.
They advertise 7,000 guns, and in talking to the owner he says he has to update the ad because they really have 10,000 on display, but that's all the room they have for them. He actually has 20,000 total. The other 10,000 are in storage.
I have never seen a collection of guns like this in my life. It rivals any museum, including the NRA museum. but AAA doesn't specialize in engraved presentations or presidential guns, etc. They just have one of everything, and most they have several to choose from, going back 300 years. Want a Colt 1903? They have about 20 originals to choose from.
Back a few years ago the prices were spectacular, but about 4yrs ago they did a massive re-inventory and repriced everything. Shame really, because now they are all about 10% too high. Five years ago I dug out a hidden Marlin 1893. They couldn't believe the price on it, so they looked it up....according to their coding system, the price tag was the original one they put on in 1979. I bought a bunch over the years, all way below market value just like that one. Not surprised they did the re-inventory.
It is actually difficult to see everything due to the dense packing. I believe it is the single most populated inventory of vintage guns on the planet.
The pic below is actually the LEAST dense section of the store, so you can get and idea of how its laid out. This is probably about 10% of the store.
My wife calls it the Black Hole. You lose all concept of time when you enter.........
