Hi fellow shooters. I am back shooting trap with my buddies several nights a week after about 5 years off. I have recently acquired two 1100 trap guns. both are 70's vintage and nice shape. looking into the future I know I will most likely need some parts. Does anyone have any recommendations on what I should buy now and put away as far as spare parts? I love the guns and they shoot very nice. I am very proud to own them. thank you, JIm
