Bob,
In Texas you don't need no stink'en permit to browse, buy, or even keep your hogleg in the car.
And as for test firing, I sure wish gun shops allowed that. Just walk right out into the street, pick a knot on a near by tree, and let go a few rounds. Would be fun but in reality a whole bunch of LEOs would decend upon you like feas on a camel.
But, if you go to a indoor range where they sell guns, yes many will let you 'try before you buy'.

Correct, there are some stipulations to the car portion though unless you have a CCP.
