I have this under the bed and it has worked great for the past 5+ years. I can get it open in under 10 seconds if needed. The only maintenance I have done is to change the batteries every 1-2 years since opening it via key is a bit of a pita.
Since you said you are new to firearms, here are some additional tidbits:
- Even if you are not required to have a license to carry, go ahead and get your license. The class requirements vary by state, but my class was all day and focused on the various laws and do's and don'ts. There was also a range component as well which is always good to practice.
- Make sure you practice. Gun ranges are pricy and classes are even more, but I would recommend taking a class or at least going to the range once a year.
- If this is for home defense, get hollow point bullets. Like many things related to guns, it has a scary name, but that is the only way to go for home defense. The advantage is 2 fold:
- Hollow points start to break apart as soon as they hit something, so the bullet will not travel through as many walls, and will likely be contained in your residence. Your neighbors will greatly appreciate that.
- The 2nd advantage is that the majority of the energy of the bullet will be absorbed by whatever it hits first. That means if you unfortunately have to shoot at someone, they will take the bulk of the energy and it will likely knock them down. Non-hollowpoints can easily pass through someone, and they might not even know they have been hit.
