My dad's neighborhood is changing (think Clint Eastwood/Gran Torino), and he has decided he wants a gun. He's ex-military, so he is not unfamiliar with them, but hasn't had one in years (he's 82). So far I have gotten him a Keltec PF9 and a nine shot Taurus 22 revolver. Due to significant arthritis, he can work the slide on the Keltec and the DA trigger on the revolver is a little too much for him. Can anybody recommend a light trigger pistol for him? He would prefer a 22 or 38 revolver. If I can't find a pistol, I thought maybe I could find him a youth model pump shotgun in 20 gauge or 410. Does anybody else has experience with this situation?
