Wow. How did I only just read this!!!
"I just got a job in gun retail. How is gun retail? Anything I should know, tips or anything?"
Firstly, congrats on the new job.
Second, to answer your questions, gun retail is a number of things.
1. in the US people are buying guns like crazy right now because of the upcoming elections. If Obama retains office, he's looking to outlaw gun purchase all together if I'm correct, or at least tighten the reigns on laws even further (which are too strict already in my honest opinion)
2. Selling guns is an easier task than one would think. Most people come in already having done research on the types of guns they would like. It's your job to hone in on a price range, a caliber, and what that weapon will be used for, ie: hunting, home protection etc...
3. tips would be to always be attentive to your customer's needs, make sure you stay familiar with the weapons because you want to be able to tell the customer details about the weapons. If you already have a strong gun knowledge then it still never hurts to keep up on current gun events and laws and merchandise. Also know your holsters, and what they fit. You want to get your customer everything they need for their new weapon. This also includes ammo types. I'm assuming you do have some gun knowledge, but I'm going to say this anyways... know the difference between full metal jacket ammunition and hollow point, what kind of ammo is more corrosive, what kind of home defense rounds will be more effective (also for those customers with children, make sure you know about the ammo that won't penetrate walls and only the perpetrator in the case of a break-in etc)
What's most important is that you do everything the right way at your local FFL dealers business, because one mess up can look bad on your company and can get you into trouble with the government. You MUST dot your i's and cross your t's in this line of work.
Also, learn fast. If you want to sell successfully, then retain that knowledge, read mags like rifleman, and check out NRA stuff.
I'm no gun guru, but I worked with a few and their knowledge was invaluable and really helped me sell the right gun to the right customer.
:) Hope that helped.
