The gender doesn't matter.Uuh... sage wisdom there Bubba... I'm sure no man has ever made that mistake.
I have never had anyone come back and tell me "I hated that gun you sold me." On the contrary, plenty have come back to say they love it, even when they came in thinking they wanted something else.
OTOH, I had a guy come in because his girlfriend wanted a Ruger Super Alaska Redhawk in .44mag as a carry gun. She had worked in a gun shop and knew the gun. I didn't try to change anyone's mind, even though I thought she was nuts, given the circumstances.
The people on this board do not represent the average buyer. They have shot plenty and know what they like and don't. But plenty of people think you can just read some reviews online for a pistol and pick out "the best one." Unfortunately in guns there is no "best one." There is only "best one for you right now." And a good salesperson will try to help the customer figure out what that is.
