Got my old High Standard 107 out today and ran some rounds through it . Shooting across top of car on sand bag I was able to get a couple one inch groups at 28 yds . It has the 7inch fluted barrel and a 5 1/2" alumalite barrel with LSP scope base . The one inch groups where fired with the fluted barrel open sights and the alumnalite barrel had a tasco 1.5X 30mm tube on it . It shot some three shot groups that where under 1/2inch . Used Federal 900B ammo . It is great fun shooting this pistol in either configuration . Nice pistols , Kenneth
