Thanks, guys, for the valuable input. I'll eventually add a number of your suggestions to my collection but I think I'll start with a single action revolver. It checks several boxes on my list, will be convenient to transport, and it's a favorite choice for my wife.
It will have to wait until after back surgery. Just gives me time to whittle down choices... but that's another discussion thread!
I'm sure I'm not alone in wishing you a speedy recovery from the surgery!
It looks like you've made your decision, and I hope that you find a great SA revolver to add to your collection. That said, I do think that every shooter needs at least one .22 in the stable. I'm going to chime in on something that
@Odd Job said.
My vote is a .22 rifle with a threaded barrel so you can attach a suppressor. With the right ammo, you will not be disappointed!
I had given that a passing thought!
I bought a suppressor a couple of years ago and it was worth every penny and every minute of waiting. It's hard to go wrong with a 10/22. I've had mine for about 40 years now, and it's always eaten everything I've tried to feed it. Now, I'll grant you that its accuracy can best be described as MOSC (Minute of Soup Can), but I've gotten many hours of plinking fun out of it. It's the bottom one in this picture:
As you can see, both rifles are threaded for a suppressor. The top one is my first Ruger American Rimfire. Polymer stocked, 22" barrel. One reason I chose it is because it takes 10/22 mags. It's a nice rifle and I look forward to shooting it more. With that said, I really wanted a target rifle, so I upgraded to a Ruger American Rimfire, Target model, shown below:
Note that the RAT also takes 10/22 magazines. So all of those mags I picked up over the years . . . now fit in 3 different rifles. So I have 3 fairly different rifles, which all share magazines, and which all share a suppressor. And they share the suppressor with my 22/45 Lite, too.
I guess the other thing to consider about the 10/22 is aftermarket. I shot mine bone stock for about 35 years. Then I had a trigger job done. Then I had the barrel threaded. And so I started down the rabbit hole of customization. Here she is now:
If you got a 10/22, there are a ton of different ways to trick it out, and lots of different manufacturers. If there's a part you don't like, swap it out.
ETA: There's one other potential downside to a 10/22. For many years, my 10/22 was the only .22 rifle I had. Didn't see a need for any others. A couple of years ago, I got my RAR and started shooting other, full-sized .22 rifles. Now my 10/22 feels a little like a youth rifle.
