I just ordered my G43 from GT Distributors last week. They estimated about a 1-2 month wait time.
No deposit, but must be picked up from store or shipped to FFL within 5 days of them receiving it.
I have bought 3 blue label Glocks from them in the past. They are the largest dealer of Glocks in Texas. They are the wholesaler to many retail gun shops.
Glock limits 1 G43 per year and 2 of any other model per year under their blue label program.
Firefighters, EMS, police and current and previous militar are eligible.
Even their civilian price of $450 is very reasonalbe. I have seen them on consignment and on "broker" websites for $550-625!
