Your camera comes with a wrist lanyard so if you drop it it wont fall to the ground.
If I was checking out a house for intruders I would think a lanyard a good idea. There is every chance I could be knocked over, and my gun would go off, perhaps under the sofa? or worse, into the hands of the intruder.
I am a great believer in not giving advise on anything I have not done myself. There's too much of that in this world. I admit I have never used a wrist loop on a sidearm, but suggest it may warrant further thought.
