Skeet shooting and other target shooting is what he plans on. I want to try and talk him into turkey hunting.
CW1027:
If the primary purpose for the gun is clay targets, the 870 is a much better choice. It will work on turkeys, doves, and other game too.
FWIW, I picked up a well used and cosmetically challenged Ithaca model 37 Featherlight at an auction earlier this year. I paid more than I should have ($275) but I wanted it and it was coming home with ME. I spent another $17.50 + shipping for a left handed safety.
Model 37's are Ithaca's pump gun. They are called Featherlight's because they weigh less than most other hunting guns. That's exactly why I bought it. However, less mass means more recoil so 37's are less than ideal for shooting volumes of clay targets.
Current MSRP for a standard 12 or 20 ga. Model 37 Featherlight is $980. Their home defense version is $800, and the Deerslayer (slug guns) run $1000 to $1200.
