Any place is a good place to start
BIG mistake.
She thinks she wants small because it looks less intimidating.
Small guns kick more, have more blast, and are much harder to shoot.
She will hate it, and it might turn her off to shooting entirely.
A full size gun that fits her hand is a better idea.
This subject seems to be coming up a lot. Take a look at these posts:
Consider a medium frame .357 revolver, which is probably the most versatile handgun there is. Load it with mild .38 Special Mid Range Wadcutter (target) loads, and it is VERY pleasant to shoot. A mild "pop" and no recoil, very accurate. Load it with full power or +P .38s, all the way up to maximum power .357 Magnum loads, and it is a very respectable defense gun.
Sorry, I wasn't criticizing. Just making a comment. I want to get my wife her own handgun and she wants a revolver and was looking at .22LRs. Can you give me more specifics of the one your wife has?
No worries, I didn't take it as criticism. It's .22 WMR (.22 Magnum) not .22lr and although it's no .45, there's a fairly substantial difference between .22lr and .22 WMR. (Especially with some of the ammo now available.)
Recoil is pretty much non-existent considering it's a 1-7/8" barrel snub nose but it is a loud little bastard. It's enjoyable to shoot, in fact, you could go through a hundred rounds and not notice it. In comparison to center fire, ammo is very affordable if you shop/order online and has been fairly easy to find even in the great ammo shortage.
I've actually carried it myself a few times when I just wanted a break from lugging around larger guns. You can throw it in a pocket holster and it disappears.
When she bought hers, Ruger had not yet released the LCR in .22 WMR but they're out now. (Although they may be tough to find.)
So far, everybody who's tried the gun has had the same reaction. First it's, "Oh well, big deal it's just a .22 revolver." But then once they shoot it, they love it. Again, it's no .45 or .357 but they are evil little bastards and I'll be damned if I'd want to take a hit from one.
