KSG15 under the bed with one tube loaded with mini-bucks and the other tube with mini slugs. Hammer down on an empty chamber, safety off and selector on the buck tube. I have ran hundreds of these through it with no issues, and it feeds them and everything else I put through it flawlessly.
My USPSA limited gun(2011) on the nightstand with 21rds of .40 Hydrashocks. Yes, I use my competition gun for home defense, it's 100% reliable with factory ammo as proven in competition, and just as reliable with the Hydrashocks. I am also more familiar with the operation of this gun than any other and can operate it in total darkness with total confidence. When I compete, I use full power factory ammo. When I practice, I use handloads that replicate factory loads and I throw in some random rounds that I know my gun doesn't like because I like to practice clearing jams once in awhile.
A Ruger Security Nine in condition one in the arm of my recliner in the living room, and my wife's Kimber 9mm in her purse on the kitchen counter. And you really don't want to let me get to the safe.
But more important than what you use or how you keep it ready is practicing with it until it's operation is second nature. And practice starting with it in the stored condition of your choice. When you need it most is not the time to try and remember where the safety, pump release or any other control is. It should be muscle memory. Practice good and practice often. We had a saying when I coached ladies competitive softball, "Practice doesn't make perfect, perfect practice makes perfect." Just going to the range and getting in trigger time and maybe practicing reloading is good, and keeps you familiar with your weapon of choice, BUT... It doesn't put those skills into play in your personal situation at home. When you are home, preferably alone, and with your weapon/s UNLOADED, practice getting your weapon into go mode from in bed like you were sleeping, from the living room, dining room, kitchen, bathroom, everywhere in the house. Practice getting to your first defensive position, and then your fallback. Think about where your family will be and what they are doing, where will they move to and what can you do to minimize their risk. There are a hundred different variables after first contact, and if you are the primary defender of your family, you have to take it all into consideration and prepare for it. What will your family be doing? Make a plan with them and practice it so they know exactly what they need to do. If they are at your fallback, how do you let them know you are coming their way? If the unthinkable happens and you don't make it back to them, what do they do. Or you successfully defend yourself and your family, are you ready for the ****storm that follows?
I could go on and on but hopefully you understand that having a defense weapon is just scratching the surface and there is SO much more to prepare for. Here's hoping you never need it!
