I feel qualified to render opinion only as a potential customer and haven't seen these mentioned.
For Range:
1) Security consciousness to include plan and ability to deal with severe ignorance, unsafe practices, and mental/emotional instability.
2) A variety of rental guns to allow non-owner shooters and to let owners try something they don’t have but might like.
As for store, I’ve learned to live in a drastically-changed world but not yet to like some of it much. I would love to read a well-considered treatise on how we got where we are from what once was the ideal gun store, the modern-day equivalent of which would be aisle 44 of your local supermarket.
I made my first gun purchase in a local furniture store. It could just as easily have been the drug store, the tractor dealership, or (for sure) the hardware store.
Best wishes to you, USMCBILL, and thank you for your service. I hope you are able to learn what you need to know in order to make your dreams reality.
