Having been the owner of an excellent-quality Taurus revo, a blued 94 Kit Gun clone with target sights and a blue job close to a classic Smith, a couple of notes-
Current Taurus revolver production is just plain iffy. You might have to go through three to get a good one. One shop we instruct at finds a failure rate on the Brazilian round guns running about 20+%. Several have not operated past the first trigger pull, locking up as poorly-fitted parts jam into a tangled mess. You probably already know that.
It pains me to say, since, as mentioned, I've had success with the maker.
Secondly, in the course of our (many) classes, we've had several women, trending to the more mature side, who've believed they could not manage semi-autos and who've outfitted themselves (or, more commonly, were outfitted) with .22WMR guns. I have to say, not one of these relationships worked out well. Perhaps it was the shorter barrels, but the blast and recoil of the .22WMR was daunting to the point of discouraging. Even I was slowed by the hellfire of the 2" versions, and I don't usually consider myself a weenie in such matters. The three-incher was really no better. Would four-plus be enough? I fear not.
One lady could not be encouraged to fire a third round out of her 3" LCR; the gun was back in the dealer's case the following week. That was not an atypical event.
Worse, at her request, I shot the gun and frankly, I didn't like shooting it, either. That, coming from a guy whose old Cobra gets the call when the beloved .45s can't be used for the ride.
We have moved towards the SP101 stoked with .38 wadcutter ammunition, which is much quieter than .22WMR and of about the same recoil. Yes, the capacity is much less than nine, but five is probably enough for nearly all cases of non-LEO incidents. It's actually a dreamboat to shoot, and the trigger can be improved, unlike almost all Tauruses.
All that said, even though I own more revolvers than semis, we still believe that Joe and Jane Average with find greater success with a semi than any revolver, as the revo's trigger is vastly more difficult to learn- we do not allow single-action firing of revolvers except in the most extreme, disabled, cases, as single-action firing is so counter to self-defense needs as to constitute a bad habit.
At the very end of the semi-auto scale, the Ruger SR-22 is a last-ditch solution for a low-power, low-effort semi (although I personally do not care for it). It's cheap and reliable and, if the user can somehow be educated as to the operation of the decocker, relatively safe for low-round-count shooters.
My apologies for the extended and possibly annoying lecture.
Winter may change to summer, but the silly season goes on and on...
