I own a few 9mm guns and the most accurate is a Glock 34. I know it doesn't have a thumb safety but you said it is for pests and plinking. I also own a Sig 320RX, a Glock19, a Shield and a Ruger all in 9mm. The Sig is almost as accurate but doesn't have a 5" barrel but you can get it with the thumb safety.
