You said metal frame and you like the 92.....
Seems like you should get a 92....
There are some of the S&W older guns that people really like and are solid options but I have no experience with them.
Honestly the p30v3 meets all your criteria except being metal framed.
If you are open to plastic frames, then honestly I would look at p30 or USPs. People complain about the triggers but honestly they are not as bad as the internet says. P30 also has decocker separate from the safety as you listed. A USP has a little better trigger and you can play with different variants. Put sights on it and honestly just shoot it. There is nothing you have to mess with or mod.
