S&W
M&P Shield
9mm
3.1"
Despite being very compact and fairly light, the Shield is the softest shooting 9mm I own, and has an amazing trigger for practical accuracy. Also, it was very reasonably priced, new.
Ruger
Single Six convertible
.22lr/.22WMR
5.50"
I have found this to be an incredibly useful and versatile revolver. I can load birdshot for moles, 22lr for cheap target practice, or change out the (included) cylinder to 22WMR for small varmints. The .22lr is also great as a trapper's caliber. The adjustable sights are excellent as well.
