I have a 5906 that I bought used and it has never shot groups, more like a shotgun at long distance. I can't see anything wrong with the barrel but I'm not an expert at such things. Have tried different reloads and store bought ammo and nothing works. With my other pistols I can shot pretty good groups so it leads me to think there is something wrong with the 5906. There is no pistol smiths around where I live so hoping to fix myself, have worked on long guns and 1911's so am not a novice. Any suggestions on what to look for or do. I really like the pistol so would like to fix the problem.
