The .22 mag is probably a nice carry for hiking. I’d have to check the Model but S&W makes one with a slightly longer barrel, Model 41 or something. I keep putting off getting a nice holster for mine. When I researched it they called it a rat gun.
Model 48
I have a LCR in 22 WMR and pair it with a Savage A22 Mag semi-auto rifle. Cheap to shoot pair.
Likewise, for more serious carry or situations, I have a Kimber K6S DASA 4” Combat revolver chambered for 357 Mag or 38 Special. I am saving up for a carbine in that caliber to have a long/handgun pair for more serious work.
My 9mm small concealable is a S&W M&P Shield but revolver operation is more instinctive and managable due to medical issues the last couple of years.
