FWIW, after reading all the comments, for a wheelgun, S&W 17 or 617. It's a smith, it'll last for ever and, it's a Smith, Their triggers are second to none, it can be smoothed and will require less finger strength than anything else I can think of. Not the cheapest but probably the best in terms of value. My wife loves to shoot but, she lost the use of her dominant side because of a stroke. we use a little Walther 32/22 bullseye pistol now but, with 0 use of her right, loading etc is all up to me.
