I would highly recommend a pistol lock box. Load the gun and put it in there. It’s safe and mobile.
Many years ago during my commercial locksmith career, I got several calls to a 55+ gated community. They have ten foot fences. An automated gate controlled by armed guards and a roving patrol.
Over a three month period I went there 6 times. Every customer was the victim of burglary. The residents and local law enforcement were stumped.
A few weeks later I got called there again. The customer told me that the perps had been caught in the act.
Three youths between the ages of 14-17 committed all of the burglaries. They were the grand children of another resident. The grand parents thought it odd that the grand children kept asking them who the snowbirds were.
