If I am under 21 will a gun store like Gander let me look at their handguns?

So I’m not sure if this is an okay place to post this but here it is. I’m going to be turning 21 next month and am looking for a ccw pistol and I have an idea of what I want but I want to feel it and am curious if a store like Gander or Academy will let someone under 21 hold and look At their handguns.
