Ruger Ranch Rifle (Mini 14) I tried to like it for years but it just wasn't accurate enough to be fun for me. I hear the new ones are better.
Years ago I bought a S&W 9mm possbly model 4609? (I sold it a long time ago) Also, just not very accurate.
I know it's blasphemy but my Colt Commander is a nice gun, it's the prettiest pistol I own, it's the most accurate of the 4 defensive caliber pistols that I own. It just doesn't quite fill a nich as well as my other pistols. I tried to sell it a while back but couldn't get a good enough offer given my investment in gun, mags, holsters and ammo.
