Just because I can't legally purchase means I have no useful knowledge or experience? That's some unusual logic for The High Road
Hmm... On the one hand, I see your point.
On the other hand, being an enthusiast and being someone whom people will respect as an expert are two entirely different things. I have no doubt about your knowledge, but I will say, unfairly or not, that I would have serious doubts about your experience.
Basically, it boils down to a saying I learned in college: The map is not the territory.
I have no doubts that you know a lot about firearms. However, when someone asks you "whats better for my wife to carry" are you going to reply with a bunch of stuff you have read, or are you going to have a knowledgable response based on experience and talking with female clientele in addition to having the ability to listen to your customer and provide recommendations tailored to the feedback you recieve from her? What if someone comes in and wants to know what the best red-dot sight on the market is? Are you going to point at the most expensive sight, or say "you know, I actually run this sight, and I like it because of X, Y, and Z".
Even if you could answer those questions from the standpoint of experience, what are you going to do about outward appearances? Look, there are customers that won't deal with a female. That's a sad truth, but it is a truth. Do you really think they are going to listen to a kid? And, if being called a kid offends you, sorry, but thats exactly what the majority of your customers are going to think, so get used to it.
And, lets not forget the professional clientele that comes in to the shop. Cops, soldiers, Marines, "operators" or what have you are not going to listen to you. Period. Get used to that idea. Until you yourself are a cop, soldier, Marine or "operator", those guys aren't going to care one bit about whatever experience you have, real or assumed.
With all that said, if you read this and think "Screw you Timbo, I DO have all those things, and I can hang with the best of them!", then friend, whats really happening is that you aren't doing a good job of selling yourself. Get letters of recommendation, dress professionally (not like a wanna be cop or Marine), and be willing to start from the very bottom. Good luck!
