Bro, I've watched a lot of videos and never heard the term bathroom gun, but not a bad idea. I have that Beretta clone Taurus P92 as well and I bought it used, the fit and finish on that gun is awesome, I knew immediately that I was buying it as soon as I saw it
I heard the term from Colion Noir, he did a video on keeping a gun in the bathroom. Had a real life news story if I remember right, just a great idea. 7 rounds is better than none.
