Since she’s British, it is technically the royal handbag, not a purse. It’s fairly well documented that she always carries a five or ten pound note for the church collection plate.
There’s a lot of speculation about what’s in her handbag in this article:
That’s probably the closest you are going to get to a factual answer about what’s in the bag. I think it’s pretty safe to say that it doesn’t contain a gun. She has guards that carry guns. She doesn’t need one of her own.
As I’m sure I’ve mentioned on the Dope before, many years ago I coincidentally discovered that a colleague was from the family that owns the company that supplies her handbags, with his elder brother being the one running the family firm at that time. I obviously took the opportunity to ask whether they have any inside info/family lore on what she puts in their product. The answer’s apparently no, they don’t.
She uses it to send coded signals to her staffers (ie if she positions it a certain way it means “I don’t want to talk to this person anymore; invent an excuse to take me away”).
When she’s introduced to a line-up of people they usually crush her hand in enthusiasm to shake hands . She keeps the thumb inside the fingers like a knuckle-duster to take the shock but keeps substances ( medical use , pain relief) in the handbag for a quick fix.
There used to be a custom - which may not have percolated up to her level - of keeping some substantial item, like a heavy glass ashtray, in there, in case the bearer needed to defend herself against some over-importunate man.
But I’d imagine it’s as simple as hanky, mints, comb, notes for any speech she may be having to make, and so on.
I don’t think she’d be able to fit a shotgun in there, and I don’t think sawn-off would be quite her style.
In common with a lot of the landowning upper class (and rural society generally, in places like the home counties village where I grew up) she hunts with a shotgun (and maybe a rifle, in my experience rifles were used by game keepers hunting for a job, not hunters who do it for leisure). Or rather did hunt, as a 90-year-old she doesn’t get out shooting that much anymore, I imagine.
It is NOT traditional for that kind of British society to use handguns (even before the handgun ban of the last 20 years or so). She most likely has never used a handgun.
If James Bond had a licence then Ma’am has one . A few years back a guy climbed the Palace fence and reached her bedroom and Security missed it . Never again .
