Are you looking for something that will give you quick access?
A few years ago I bought a small gun safe lock box from Cabelas that is about 12"X9" or so for handgun. It opens by two means, a key or five finger combination. I use the key method only. It's childproof as long as you don't keep the key in it. Since I keep that key with my other keys I always know where my keys are in the morning. I'm sure it can be easily installed in a wall.
Once you have small kid running around the house you have to give up easy access to guns and keep them locked up. That's just the way it is. There is a much greater risk of a child having an accident with a gun unsupervised than there is of a home invasion while you are home. Children are children. You can make them memorize every single gun safety rule there is and even be proud that they can recite them from memory. BUT, no matter what, children do not fully comprehend those safey rules until they get older, no matter how well you've made them memorize them. No resposable adult gun owner would ever allow a child easy access to a gun, loaded or not, without supervision.
Thanks for the reminder. I am a L.E. firearms instructor ( retired ) with 5 kids and 3 grandkids. That is why I am looking for concealed childproof ideas. Better keep your handguns unloaded, kids know how to use keys too.
Over the years I have seen several elk and deer hides left in the woods by hunters and I have to wonder why they do this? I fully understand and agree about getting the hide off the animal as soon as possible to cool the meat, but why not pack out the hide with you and use it? As far as I know there are no state laws that require you to take the hide home, but to me why waste such a beautiful part of the animal? Some might think they have no use for the hide or it costs too much to tan....
