Don't bet on it. My Taurus .357 offers no protection against theft when it's locked in the gun safe and I'm 20 miles away at work. There's just too many professional burglers nowadays driving up to houses mid-day in commercial vans that are painted to look like contractors, plumbers, electricians, and custom kitchen remodelers (sorry Jeff). They ring the door bell to see if anyone's home, and when no one answers, they simply walk around to the back of the house and break one window in the back door and let themselves in. They then open up the garage door and start loading the van up with all your stuff. I know four people this has happened to. Because of this type of burglery, many of us up here in snow country have our driveways plowed regularly when we go on extended winter vacations. Nothing signals to theives that your house is empty like a driveway that sits unplowed for 5 days.And take pictures and get appraisals on your drums even if you're covered for $50,000! Your insurance adjuster is not going to look at a charred, melted snare drum and take your word for it that it was a $2500 wood Dynasonic.
I don't have a gun case my guns are placed in my home in places that only I know where they are at and they are loaded and ready to fire flip off the safety they are firing, I live alone. I have a carry and conceal permit and do carry. I live three minutes from were I work. I don't have a garage, I have a very good home security system with live video feed too my phone. We have a very good neighbor hood watch program with my two closest neighbors retired military. I have all my drums recorded on video with identification such as serial numbers, special marking etc all noted. I have a special writer just on my musical gear alone. I am not saying it is full proof but a thief would have a bad day at my house performing a crime. In fact a moron thief tried to break into my house just a month ago they are in jail now. They successfully broke into 4 other house in a surrounding neighborhood. I got him and his driver.
