Honestly, most folks who only have 1 or two guns at home that I've had experience with haven't had safes to keep them in. Growing up (and to this day) my folks have the .22 rifle in the closet with the bolt stashed in a sock drawer and the Luger down in the cedar chest that all the winter sweaters stay in. My BIL doesn't have a safe for his CZ O/U. My hunting buddy didn't get a safe for his firearms until his son was born. One of the biggest collectors I've ever know of C&R stuff used to have everything stacked by the stacking swivels in his apartment and kept a loaded Thompson SMG (in semi) on his night-stand.
That said, I have no doubt that the vast majority of us on the board, being serious firearms enthusiasts in any number of ways, take our safety and our investments seriously and keep them in locking cabinets or safes. Shoot, as I said in the Walmart vs Amazon thread, I just ordered another Stack-On for my collection.
I'd say that their conclusion of "more than half" probably isn't too far off the mark. Think of all the Bubbas out there who keep a shotgun next to the front door at night, or just leave the slug guns in an open rack on the wall. We, as a community, have to be a lot harder on our fellow gun owners when we see that they don't have a safe method of storing their arms.
Put "Hopkins Study" and "Gun" in the same sentence and I'm reaching for the manure fork.
I have a few ways to lock up guns - 2 safes , cabinets with locks , and metal boxes . I have always felt a need to handle my guns with care and to reduce the chance of them being stolen .
I would like to see the questions, their sample size. I do a lot of analysis at work, and a survey can easily be warped.
