Glad to hear that you are dealing with this on a less emotional basis. As far as I am concerned, dealing with the loss of a spouse could cause a lot worse of a reaction than yours, i.e., getting mad at Ruger, so don't be too hard on yourself.
My guess is that most or maybe all of us at some point have purchased something only to see a better option become available shortly thereafter, or maybe purchase something that after we research it we think it will be perfect for our need, only to have reality smack us upside the head. I have found the best way to deal with it is to get rid of the item, by trade or sale, even if you have to take a significant loss, and move on. And specifically with guns, I can remember when I bought an LCP thinking it would be the absolute perfect concealed carry gun (and there are many folks who think it is) but I found shortly after I bought it that I could not fire is well, I hated shooting it, and I decided my original dislike of the 380acp cartridge for self defense was valid (in my opinion). I held onto this gun for years but felt annoyed everytime I looked at it. I've had others that led me to be disappointed (like the one and only Kimber I ever purchased) and at first refused to take a major loss on it, but eventually I decided life is too short to get upset at such minor things.
Good luck with your shooting now that you have returned to the sport. And best wishes for a good life.
