My first handgun was a SIG Mosquito. .22 LR is the perfect starting caliber, and the Mosquito feels and functions like it's big brothers (something the Rugers, Hi Standards, etc. lack).
Long gun was:
Savage 22 over and 20ga under 28 years ago. Kill a many varmits with that gun. I still have it and wouldn't trade it for the world. Thanks Dad
