old lady new shooter,
I have to agree with fellow THR member Partizanai from The People's Republic of Maryland, Slave State...even though I'm in the Free State of Colorado! ;-)
If they don't SEE it and can't FIND it, they can't STEAL it!
Simple...the KISS principle.
In your case, with just ONE handgun (and ammo for it, of course), your BEST bet is to find a very "unique" hiding place for it that most thieves -- who are EXPERTS at finding so-called "hiding places" -- wouldn't look.
Aside from simply hiding it, you could get a serious (meaning at a minimum, a Class B rated) steel security safe but you WOULD have to bolt it down to keep it from being moved. And have no tools laying around in your home or garage they could use to TRY to get into it -- or pry it from the mounting bolts. Or use your dolly/hand-truck to carry it off!
A Class B safe, as it uses thicker steel (and steel is expensive) will cost you at least $$$ but more likely close to $$$$. If you don't mind spending the money, however, then you could get a safe big enough for your 1 gun, some ammo, and maybe some small electronics, too -- camera, phone, laptop, plus important papers/documents -- so it wouldn't be ONLY for guns.
For personal example, I have a small Class B rated steel security safe right now (a "Cobalt S852C") for some of the small stuff I mention above, but only handguns will fit into it, no long guns. Still, it's better than some thief getting ALL my guns and smaller valuables/papers (especially with Identity Theft being a big deal nowadays).
But the good news is a Sturdy Safe (Model 2419, with thicker steel and HARDER to get into than my earlier $4K Liberty Presidential was!) is on its way to me and then I can secure my long guns, too. And if I want, I can bolt my smaller safe to it to make it even more cumbersome/heavier to move.
Yes, I have a separate floater/rider on my Renter's Insurance policy for my guns, but I PREFER not the have them stolen in the first place, mainly because a criminal will then have them -- and no good will come of that! So even though they're insured and I can go buy them all again, it's just the responsible thing to do: Lock them up.
Again though, in YOUR case, you may want to just HIDE the gun...
But if you have the budget and inclination, a small safe would do for your gun and other stuff. Perhaps one like the "Cobalt S838C" is plenty big for 1 handgun, some ammo, and small electronics/documents. See it here:
https://www.totalsecuritystore.com/cobalt-s838c-heavy-duty-security-safe.
And being Class B rated, it's some serious steel some street-trash low-life will have get through...not so for most RSC "safes" (Residential Security Closets) out there (even the top-of-the-line $$$$ RSCs), or those small "Gun Vault" type handgun "safes" made of thin sheet metal.
BTW: the Ft. Knox Pistol Boxes are the best your can get for a car, steel-thickness-wise, and have FAST opening Simplex locks -- even without looking and even in total darkness. I have 2 of these in my car, bolted down!
Or go with BOTH security methods: (1) HIDE your gun and (2) get a safe for small electronics and your important papers/documents. The bad news is a safe says "steal me" even if it's EMPTY (how would they know it only has some bricks in it) and so focus on your safe...and maybe stop looking for your gun. But if your safe is "serious" and they can't get into it or move it, then your stuff IN it is still protected, and your gun, too, as the safe distracted them...at least it may have taken them too much time and they didn't want to risk staying longer working on it. But who knows, just a thought...
Whatever, that's why bolting it down it REQUIRED!
No...none of these Class B steel security safes have fire-protection, they are rated for burglary protection, not fire. And most so called "fire-rated safes" (just RSCs with sheet-rock liners) use way too thin metal -- one with fire protection AND Class B burglary would be very expensive. So I prefer to go for BURGLARY protection vs. FIRE. As for fire protection, there IS a way to have that with these steel security safes (which I do)...but as mentioned, MY main interest was not fire protection, it was burglary protection: I don't want my guns in the hands of criminals. In a fire, they'd burn up and I buy new ones, but at least no criminal gets them -- the fire did! ;-)
Still, the most cost-effective way to protect valuables is to HIDE them! But
you really have to have a good place as most thieves KNOW exactly where most people "hide" things and they find them faster than you can say "Gone in 60 Seconds." Or faster! ;-)
Good luck...
P.S. Here is where I got my Cobalt S852C:
https://www.totalsecuritystore.com/...t=2+1000+1005&start=49&ppp=12&sortby=priceasc
These guys (TotalSecurityStore) have the best pricing I've seen...and shipping is included (a big deal given how heavy these are). Whatever, DO NOT pay MSRP for one, as SOME stores will charge you! For example, one site charges $838.37 for the smaller Cobalt S838C. And for my Cobalt S852C ($647.99 @ TotalSecurityStore), they want $1001.02! And then probably SHIPPING on top of that! Outrageous!
Shop wisely...and buy from a reputable dealer only!
