If I only could have ONE pistol for all shooting needs/wants, it would be a .357 Magnum. Fortunately, I am not limited to one because my favorite pistol/caliber is the 1911 .45 ACP. But again, if I was limted to only one option, it would be the .357 mag. as I (Capital I) think it is the most all around useful caliber. As I think about it, it is funny as I hardly ever shoot my .357 magnum (Colt Trooper) these days (too many other toys). Damn, I wish I had not sold my 8" Python 25 years ago!!!!!!!!
