I'm disabled myself and I know what it's like when the Doc says sorry no more work for you. The trigger is a must and the next thing will be an adjustable stock, right after the stock will be a really good scope (can't hit what you can't see), then you can start shooting groups and see if the barrel is very good and what ammo it likes. Keep us posted and good luck. God Bless you and your family, and thank you for your many years of service.
