My target shooting over the past ten years has really gotten terrible . It got to the point I didn't want to shoot with friends and neighbors because I was getting so bad . I've got a Ruger .22 with red dot sites that I can shoot pretty well . I also have a Glock 17 Gen 3 that I bought in 1999 and still have . I never changed much on it since I bought it . I did buy an after market barrel , polished the trigger assembly but not much else . I could shoot it pretty well for about 12 years and then my eyes started getting worse . At 25 yards , I was lucky to get half on paper at all and I'm talking a two foot square ! About a month ago , I finally broke down and bought some good fiber optics sites . My shooting has improved a good 70% . Now at 25 yards , I have yet to hit my two inch Bulls-eye but am getting way closer . 28 of thirty shots are all on paper now , a much greater improvement ! Maybe I'll put a rifle scope on next , 3.5 X 50 ....?
