+1I can't say what the worst gun I ever owned was because I never owned a bad gun. I was advised when I was young not to buy cheap guns. Work harder, work longer, and buy quality. Good advice. I see young fellows at the range often plaguing themselves with newer guns I wouldn't own if they were given to me. My best guns are the old Sakos.
I would have to say my worst guns were both poor examples of guns generally known for their quality. One was a buckmark camper and the other a ruger 10/22. Both jammed frequently. Both were sold.best.. i ain t about to pick anything over my s an w 60.. but some day im gonna own me a buckmark camper..never felt or shot a handgun that i thought was made better in semi auto..well my 225 sig was sure something i hated to let go.
worst is easy.. never owned as sorry a gun as phoenix semi auto 22.slim
