I think it has more to do with what the retailer wants to tie up his money with than Eagle Imports. I went to two local shops that are listed as dealers for both Firestorm (sgs-firestorm) and Bersa (Eagle Imports). I was looking for the compact 9mm version of either model. I wanted to compare them side-by-side. Niether had either one in stock. They both had multiple .380s, though.
It seems that the .380s are more popular than the compact 9s,.40s, or .45s so that is what they stock.
Both offered to order what I wanted, then tried to steer me to something on the shelf that's more expensive. That's their job, no problem.
Both times, I bought a box of ammo, just to let them see that I had money in my wallet, and wasn't just wasting their time.
No. I haven't used any of the on-line auction houses. I too want to handle a weapon before buying it.
There's a company that sells used guns that I watch regularly. They mostly sell police turn-ins, or estate items. Thay also get new and refurbished Glocks, SIGs and HKs. It's not an auction house, though.
