As an NRA instructor (USCCA - you’re next on my list of certifications!), aside from hosting classes, I have offered to take any of my “day job” coworkers to the range for an hour to teach them the basics of pistol shooting for free, and have had a really good response from them.
What are other ways that you all use to bring people over to “The Dark Side”? 
Great topic. I have brought my mom, sister, and other family members over and all are now concealed carry, and some uscca members. I found that they simply feared what they didn’t know. A good 4-5 hrs talking about the nomenclature, safety, and responsibility of firearms (and several hrs on the range) brought them to the understanding that its simply a tool that will do what you instruct it to do. Which can possibly save your life.
I’m lucky enough to work at a company that does not restrict our ability to “conceal” carry and there are at least 6 of us that do. We also have several young women who live alone or whose spouses travel leaving them home alone. I’ve offered to take any of them to the range at any time they want to go to teach them gun safety and help them get familiar with firearms. We recently had a threat against one of our female employees so all of us were on a much higher alert level than normal. Several from my team come up to me that week to tell me they felt much safer knowing there was an “extra” level of protection in the office over and above our locked glass doors and panic button…
I’m a NRA Certified Range Safety Officer and an Affiliate Firearms Instructor with USCCA. I also use to run one of the shooting divisions at my gun club. And I do volunteer at my gun club when they need extra help at their main range during the holidays. I also wear PRO-GUN SHIRTS that I have from all of the groups that I’m a member of or belong to. And those are the NRA, NAGR, their FRONT LINE DEFENDERS, JPFO, 2A FOUNDATION, GOA, and of course USCCA. I have also helped people at the range do their shooting and handling of firearms safely. And have even taught some kids how to shoot and follow firearms safety. And I love doing it as well.
Well, I have a hard time converting my co-workers 
I have converted a number of family members and friends of my mom’s who were very anti-firearm. I haven’t gotten all of them to shoot, but I have gotten them to understand the different terminology and do some research for themselves (a lot are in the education field and love research, so I’m using their interests to help them understand firearms).
The most important thing is to be responsible. Open carry, while legal in my state, sends the wrong message to the non-gunner. I laugh when I’m at Walmart and see one of the local God old boys with his lama .45 and a cheap nylon holster. Professionalism and respect for the other guy signal that you are a responsible gun owner.
I simply try to maintain general enthusiasm about the subject of firearms and shooting. It is no secret to my family and friends where I stand on guns. However, I am NEVER confrontational about it. I simply try to inform those who are curious, and I regularly invite folks to the range. Even if I get only one or two to take me up on the offer, that’s a win in my book.
Pro 2-A shirts, hats, and my USCCA gear. I even wore my IGOLD(Illinois Gun Owner Lobby Day) hat to kids church camp. I will politely have a conversation with ANYBODY to demonstrate the Pro-2A lifestyle, and I volunteer to take “new” shooters to the range whenever I can.
As a retired military officer, I usually express concern when I hear others refer to assault rifles in a negative way. First of all, I believe using the terminology; “assault” is incorrect. As a comparative illustration; I inform others that until shortly after WWII, the Department of Defense was formally known as the War Department. That nomenclature implied an aggressive nature. Being the peace loving country that we are, it was thought that being labeled Defense, would give a more conciliatory de notation as well as connotation. The mission of the War Department never changed. It always was and still remains to Provide for the Defense of our Nation. The same can easily apply to what are currently referred to as Assault Rifles. If we referred to them as defense rifles (which is what most people purchase them do) then the negative stigma attached to them could be greatly reduced. There capability would not change, but the connotation would. Our military is constantly striving to have the best weapons for our Department if Defense, so that we are not out gunned in our peace keeping missions. Private citizens should be afforded the same opportunity to provide protection for their family with rifles capable of at least matching those of persons who mean to harm them. What better way than with a Defense Rifle. So, that is what I share with those who are against assault rifles. Many (OK, a few) have said; they never looked at it from that perspective.
I have gifted .22 LR rifles to various nieces, nephews, and grandchildren. My go to gun for this is a Henry Lever Action rifle. I have also gifted a Remington Model 66 Nylon and a Marlin Model 25. The gifts were in every case, their first gun. We usually get the larger family members together and shoot a few times a year and I bring a variety of guns for everyone to try. Some of my nieces and nephews have been able to shoot a Thompson Machine Gun (a range rental), an H&K MP5 (another range rental), a FP45 Liberator, a .475 Wildey Magnum, and many other guns.
I feel that getting people to shoot and have fun is essential to promoting a Pro-Gun sentiment.
Love your approach to this @Richard40 - your position as a retired officer probably gives you a little extra leverage in helping people see things in a different light. Which military branch were you in?
And from one military family to another, thank you for serving!
Love your style @Borisd63 - That’s been our strategy with our granddaughter, and will be with the great grandaughter. Next up: nieces and nephews
I go out of my way to engage folks pretty much wherever I find them if they seem the least bit amenable to discuss gun rights, carry rights, and the joys of shooting.
I don’t have kids of my own but will give any youth who’s parents will give permission a basic introduction to rifle and shotgun shooting and give them some opportunities to hunt and fish as well.
As an outfitter and guide for many years I’d usually get at least 2-3 calls from busy professionals with kids who had an interest but mom/dad or both were too busy or no experience themselves and had no clue where to start. I’d usually make them a package 5-7 day deal to send their kids to me for a week of “rednecking”. A basic introduction to guns, shooting, varmint/predator, and hog hunting for little more than my cost and several of those kids ended up coming back later in life first to work for me during vacations helping with the dog training and guiding in exchange for some hunting of their own and I still managed to get paid on top of it.
Some of those kids are now coming back with their own kids and that is amazingly gratifying.
I also open carry frequently where legal simply go generate conversation starters and to be a good ambassador for lawful carry. It has proven in most cases to be very effective with hundreds of positive interactions and only two that were decidedly negative. One of those resulted in a protester spending some time in the hospital and quite a bit in jail. They other was just a lost cause from the start and a horribly nasty woman at heart.
I’ll take the occasional loss though for all the good I see us doing.
Thank you for your comments. Army. Best wishes and thank you to your military family. 
@Richard40 My husband was Special Forces in Vietnam, my dad and uncles were Army. We’ve got Navy, Air Force, and Coast Guard… so far, no Marines.
I’ve offered to answer anyone’s questions related to firearms, shared news stories of people defending themselves with firearms (to counteract the mass murders that get re-hashed numerous times per incident making them seem common), and I also shared related articles that your organization has provided. Finally, people who know me know I contradict the stereotypical firearm owner those against the 2nd amendment like to use.
