Here's what ya do:
Go to Buds Gun Shop
Click on 180 days to pay
Find a good, new in the box, armory grade semi auto handgun
This way, you can get a quality firearm under warranty which is important since you are a professional
Put 10% down and pay it off in 6 months
When it's paid off, you have it shipped to a local FFL. Mine charges me $25.00.
I do this. Just got an M&P 9. As soon as I get one gun paid for, I put another one on lay away.
Check back frequently. They add different guns almost daily.
They also offer discounts to professionals.
