I got a 590A1 propped against the nightstand, G19 on the nightstand, how much more can you be prepared??? Only thing I'm missing is an AR. If that can't cause a "stop" within 50 yards(a house), I'm WAY out gunned.
I'm more for tactics. If all I have is a G19, you better believe I'm a "stopper" with it when using it for CC, HD, or just plain ole' fun.
12" barreled AR with eotech, surefire G2X Tactical, and three 30-round p-mags and a Glock 22 with a Streamlight TLR-1 (300 lumen model), Trijicon night sights, and three spare mags is my personal bedside arsenal but that's because I'm comfortable with that setup and I carry them everyday (except the 22 since we recently transitioned to the 17 at work). One big factor in my choices is that my wife is also comfortable with these. I asked her if she wanted a 9-mil but she'd rather have the full-size .40...I couldn't have been more proud.
My personal choice is a Sig P239 with night sights. It sits right next to my high output tactical flashlight. I chose the Sig because I can shoot it very accurately. I chose night sights and the tactical flashlight because if I have to use it, it will probably be dark. Whether it be shooting a silhouette with night sights, or shooting at a blinded target basking in the flow of 200 lumens, the Sig will get the job done.
Try this approach. Downstairs I have a 92.3 lb Doberman pinsher named Sollie. If anyone walks in my yard or close to my home he wakes me up. I grad my shotgun or my 9mm...maybe both. My point is a dog who barks is the best first line of defense.
I have a special holster that mounts to the headboard right behind my pillow. I put my 1911 Colt Defender or my Springfield Ultra Compact there when I hit the sack. I practice with both guns at the range every week and keep all my shots pretty well centered on the target. I know it will be a whole different story in a real live situation than a stationary target but those two pistol's are the ones I shoot the best. I like the night sights on the Springfield but also feel pretty confident I'll do just as good point shooting the Colt Defender. I have been confronted by three to four punks twice in my lifetime which resulted in having to pull my gun on them so at least I know somewhat how I'll react in a similar situation. The time I served in the military have helped me to develop that.
