Push-button w/ keyed backup.
GunVault MiniVault for me. Pretty sure I have the GV2000S. Mine has the shelf in it.
It can comfortably fit 3 holstered firearms + reloads.
ETA: When my first born wasn't yet mobile, I'd open the thing at night and then close it in the morning when I got ready for work. Now that I have 2 kids that are old enough to seriously get into trouble - it's locked almost 100% of the time unless I'm removing or reinstalling something.
And I HOPE that I never have to open that thing, at night, and in a panic.... But I still wouldn't trust a biometric one due to what has been stated above.
I have several since I have kids. Sadly, the 1st gen is MUCH better. (runs on a bank of AAs. newer ones use a 9V) My first one feels almost like the unit is registering keys before I can press them. I cant outrun it. My newer 9V powered unit is sluggish and I have to be careful I dont press them too fast. I even had the factory replace it and the new one does the same so its not a fluke.
I ran a test using the newer, slower GV and my SIRT pistol/LASR trainer. At the beep, it was actually faster to retrieve a "loaded pistol" from the GV than it was to simulate the "kid safe" unloaded pistol on the nightstand where I had to pick up the gun, insert the mag, and rack the slide before using.
