I’ll say it works! When we were doing the 17 Design buy and Sooner was doing the background check, I did just like you, looked around till it was done.Sooner's web site says they do 75-100 FFL xfers per day. Let's go with 100/day. If even 1% of that 100 buy something, it's 25-30 additional sales per month they likely wouldn't have gotten. I'll look around while they run my 4473 so pretty good tactic to get someone in the store.
But in the meantime I found a Freedom Arms revolver and it went out the door with me.
